DNA, Chromosomes and Genes 

this guy is literally getting me through my biology exam

I've used your videos during my prerequisite classes for nursing school to understand these kinds of information and I still continue to use your videos to brush up on the same information! I just love how well you break it down so if someone didn't know what chromosomes, dna, and genes are that they are able to understand and put it together. Please continue to make videos!

Wow! My grammar is poor when I'm excited :P What I was trying to say was thank you for this very simple but informative video on Chromosomes and Genes. This was the exact video I was trying to RU-vid search to help me better understand my textbook titled "The Developing Person Through Childhood and Adolescence." I'm reading chapter 3 titled "Heredity and Environment." I especially enjoyed the DNA recap at the beginning. What was taking me an hour to read you explained very well in a manner of minutes. Now I have a better understanding of where the Adenine, Cytosine, Thiamine and Guanine fit in with DNA. I also have a better understanding that DNA is in the Chromosome which are in the nucleus of a cell. I'm literally jumping for joy at this simple explanation. I work at a Montessori school during the day, take ECE and Psychology classes at night and so you can probably tell that when it's time to read my textbook, it's either late at night or early in the morning. Your presentation is excellent! I can see your face (that's important to me for some reason), I can clearly read your notes and you picked perfect pictures to describe what you're talking about. You're basically my official RU-vid Tutor on Genetics. Keep up the great work!!!

I am a nurse studying for my Oncology Certification Exam. Just wanted to let you know how helpful this video was and how much time it saved me in trying to understand this information. Your students are very fortunate to have you teaching them. Keep up the great work!

Tyler Dewitt and you explain very well and in the same manner (camera views)

Miss Kimberly Joy Thank you so much. It is really rewarding for me to hear that my videos are making a difference. It's an honour for me to be your Genetics tutor!! All the best Jeremy

Not sure if you read your comments, but i wanted to thank you for these videos. They're so clear and really help me with studying for my biology tests!

I am a 54 student who learned English late in life. I found your videos are very clear and you have a natural style of teaching. I encourage you to continue. Thanks a lot

The flow chart if you want to call it that of the chromosome, DNA, and genes at the end is a wonderful way to put it all together. Thank you so much for that

Your diagram of DNA, gene and chromosome is exactly what I needed! Thank you! It really gave me perspective and helped me understand their relationship. Until then I only had separate concepts of the three ideas

This guy is about to make PBS and the BBC obsolete. What a master at breaking down complex subjects to everyday language. Thank you, Mr. LeCornu!

Excellent explanations and visual cues as well as breakdown of the more complicated topics! I've found that most videos seem to jump from one part to another without managing to link each part cohesively in order to give a bigger picture which you have all done, thank you!

Thank you so much. I have been on-line trying to figure out these basic principles and only got confused. You have simplified the complexity others had presented into easy to understand learning.

Thanks so much for breaking down these concepts, most of what i found online where not really this clear and direct!!

i like how you teach, you basically fill in the gaps to make us understand the full picture in detail.

You area great teacher. Thanks for taking the time to share your impressive knowledge. Now I am starting to understand this complex concept thanks to you.

The way you explained this concept was so simple , lucid and precise. Thank you..

Thank you for breaking this down in a way that makes sense!!

I have never ever watched any presentation as u did... Ur really best...simple but most informative

You're welcome! I'm really glad it helped.

i have always thought that these complex terms are much complicated but u made them easier. thanx awfully. hope u make more videos.

This is the best explanation I have found on the internet. I'm taking an online genetics class and I wasn't getting a good grasp on these three terms. I'm apparently a very visual person and needed a solid picture in my head of what these are. Thank you so much!!!!

Thank you Mr LeCornu. You made it very easy to understand. Thank you for taking time to make the knowledge available to everyone. You are awesome

You sir are a life saver! Thanks a bunch, Cheers! ~ Dee

Thanks Mr. LeCournu, I am a seventh-grader from New Jersey in the USA and currently being homeschooled. I like seeing your videos for help/reinforcement with science concepts.

It was the best explanation I've found...so simple, so understandable and useful alot. Thank you very much

Thank you for making this video Jeremy. It has helped me understand how DNA and Chromosomes work. Much better than my professor.

This is the best explanation video; simple, easy to understand, well-illustrated, right to the point. Thanks a lot!

THE ONLY CLEAR EXPLANATION THANJS I WISHED I GOT HERE SOONER

thank you so much, youve made it so much clearer!

Great explanation and very simple. Please go ahead for other confusing biology terms if you can. Thanks for this video

Thank you Jeremy. I was trying to understand the relationship between chromosomes, DNA, and genes. I wanted to know what is the smallest unit. Thank you for your video; it made the relationship among the three crystal clear!

thanks so much. You helped us to connect the dots and filling in the gaps we missed between lectures in school :))

Exactly what I was looking for! Thanks hanks for making an order in all these terms

Excellent presentation and explanation of difficult subject matter. I don't know why other professors don't break this subject matter down so it can be underestood. Thank you for helping me understand!

Thank you so much!!! This has cleared up a lot of confusion for me!!

Very good. Well explained. First time I have actually understood these things.

You have helped me so much in my Microbiology class! Thanks!

u are basically the biology version of tyler dewitt u guys both explain very well thank you

WOW - perfect presentation, easy to absorb and well presented. thank you so much

Sound and clear. Thank you for making this video.

Hi- I love your videos--they are so clear! We are watching a course in genetics, but I have to turn to you for actual information that I understand! Is there a suggested order in which to watch your segments? If yes, can you tell me where it is? thanks Karin

An absolutely clear explanation, well done lad. It's a shame that 15,696 whatched the video and only a few left a comment or pressed the "Like" bottom.

Absolutely great and simple explanation you sir are to be labeled a master thanks been trying for years to understand what you said in five minutes OMG thanks

Thanks a million for your educative videos. They help me to know more about living organisms.

GREAT! I LIKE YOUR TOOLS , AND NOW I FULLY UNDERSTAND EVERYTHING! YOUR METHOD OF TEACHING IS EASY TO UNDERSTAND , VERY BASIC AND HELPFUL... THANKS! GREATLY APPRECIATED

Very cool info, took some notes ^^ Thank you!

thanks for the video, it has really clarrified some points i was not sure on. It has really helped me out!!!

Thank you so much sir I pass my first generation genetic semester

i m so impreciation about your explanation so thanks you so much mr jeremy lecornu

Hi there.. thanks for the video.. totally helpful for me.. :)

It is a very good video Sir. It helped me very much to understand DNA.

Great video bro, all the best and thanks

Very interesting video! This really helped me thanks!

you are a fantastic teacher. thank you so much.

Awesome video!

i have seen the best dna video in my life verry good explanation

fist you way better than my teacher u explained the whole thing just in 13mins and my teacher made it about 1h. And the second thing is you speak a bit to slow so when i put the speed to 1.25 it's more fit me

This is really wonderful explanation very easy to understand Thanks a lot 💐

Thank you for this.✨

thankyou sir . impressed by the white back ground and white sheets idea creative

really great breakdown and delivery! i finally understand! oh wait... it never ends :0)

Waaw it was a superb explanation which helped me clearly understand the distinctions between dna , genes, and chromosomes ....now i am able clearly relate them about how , where and what they are ....thank you......❤️😀

Excellent! Thank you.

This is wonderful thank you

slow speaking and eaisier to understand than my science teacher.... thnx^^

you helped me a lot

I like how you teach!

Amazing, thank you!

Thank you so much, please make video aboutn topic on Gene mutation in SCA disease

Thanks so much. I was always confused about that X shaped chromosome now i know in which stage it is

Because the way you present the information makes it easier for a layman with almost zero knowledge on the topic like me to grasp and help construct the picture the relationship in my head, I've subscribed for more videos of yours. I have a basic question, though, that your clarification would be much appreciated: Is it true that in the process of fertilization, when XY chromosome becomes unsuccessful, the attempt will revert to XX chromosome which is the default state? I'm not sure if I devised my question properly because English is not my first language, plus being new in the domain of knowledge. Thanks!

Hello, thanks for the explanation. It helped a lot. Question: is there DNA outside of chromosomes, or do chromosomes categorize them, or what? Thanks in advance.

nice sir appreciate ur knowledge. ........ solute u sir.

Thanks just bcz of u my doubt solved😊

you are a great teacher thank you all British teacher are great

good teaching sir

Thanks sir your video help me competative examination Very good wishes stay blessed

hey jeremy, your videos are great !! I tried looking for videos on alleles and punnet squares on your page but I couldn't find any? (:

Thank you so much☺️ !!

Thanks for this, really helped me better understand, especially that genes are just part of the DNA, but DNA has to combine with the proteins to make chromosomes.

Very good.

OMG This gives me so much help... Thank u very much for posting this video. Thank u😭

Thank you so much 💜

Thank You so much!!!!!!
