You make a lot of sense, which pretty much never happens for me in science. You explain the basics in a repetitive, simplistic way that makes it easy to understand what I need to know to pass my science class
Education never expires, it's a timeless gift that keeps on giving. Your video uploaded 11 years ago in 2012 is still enriching lives in 2023. This is truly remarkable! Thank you for your unwavering dedication and contribution to millions of students around the world. Your knowledge continues to be a beacon of inspiration.📚🌟
Thanks! It's helpful to watch the video before I read the textbook. This is my first biology term in the U.S. It can be challenging, but I will do my best for my own knowledge. I can play many of your videos over and over again, that's perfect!
Elsie Haris Its also help me a lot...Tomorrow is my biology exam...I was studied 2h on nucleic acid....But, everything vain.!Here I understand everything! WOW
We should put your DNA to all our Biology teachers! Sir you are saving my life with your videos, I hope that you understand how much you help thousands of students! God bless you!!!!!
I really appreciate your struggle . You deserve something mindblowing.I am from Pakistan , I understand you lectures as of my own teachers. Would that I could download your mind also!
THIS IS REALLLY HELPFUL FOR EVEN FOR SOMEONE LIKE ME IN 2024. LOVED THIS VIDEO AND IT IS REALLY VISUALLY PLEASING TO LISTEN TO AND THE PROF'S VOICE IS REALLY GREAT
Key takeaways: -RNA and DNA are different bc they have different sugars, they also look different -they makeup out genes -they each hold specific bonding
Have a mock in A-Level Biology tomorrow, thanks so much for the revision help, I learnt far more from your video than my Biology teachers at my sixth form.
I LOVE YOUR VIDEO. I am Chinese and I have just moved to America for a short period of time, and your video helps me a lot in ap biology as always. I can see your hard works and keep on going.. you are an awesome biology teacher :) !!!
Omg thank you sooo much. I didnt understand my professor teaching this for hour. But in your video only few mins, I got it right away. Thank you again.🙏👍😉
Trick for memorizing purines vs. pyrimidines: the first letters of adenine and guanine are Ag, the atomic symbol for silver. Silver is pure (PURE-ine), while a cut (cytosine, uracil, and thymine) are not. Hence, adanine and guanine are purines, while the others are not.
Helped dramatic with study notes and revising for assignments and SAC topics. Thank you so much, no doubt i will be watching your videos for further information and revision. Great examples and a clear explanation. Thank you.
OMG!!! this really helped me for my tomorrow` tst !! had really hard time to understanding this all concepts bt u clear it up.......... thanku sooooooooooooooooooooooooooooo much sir!! :)
I'm from Indonesia..I Like ur video Mr.Anderson,,bcause i understand about nucleic acid after looking your explanation in the video..I thik its not easy,,thank you..:)
But if 2RNa's overlapped, shouldn't there be a strand of like 2 Uracils. In the DNA picture, It shows there is Thymine bonded with another nucleotide. Where did the thymine come from?
at about 4:15 Mr.Anderson said that is how RNA is made.... but in the chain there was Thymine NOT Uracil ...Does that mean in the RNA chain you can have both T and U?
Brysoneum Owen I learned this in 9th grade as well, and in 11th grade but I'm learning this in uni right now, again XD school is kind of repetitive sometimes
I'm here studying for my anatomy and physiology exam today. It does give a little extra boost than how it was explained in my class which is really helpful
Quick question, do you have a video where you teach how the scientific terminologies are to be pronounced correctly? I have big issues e.g. pyrimides I almost pronounced it like "pyramids". Any help on how to pronounce these words will be very appreciated.
i think u made a small mistake.When you gave a explanation of how RNA are made by using covalent bonds u used Thymine but u earlier told that rna doesn't have thymine
Hello Sir !! Thank you for your Videos for better understanding of these topics. I have one questions, at 4:46 minute .. the guanine and cytosine which are to be base paired are placed in antiparallel way as 2 DNA strands are antiparallel ! Clear ! But when I tried to establish hydrogen bonding between these bases, its not working ! Both the NH2 groups are coming on the same side and so no hydrogen bonds ! Then I drew both bases parallel and the hydrogen bonding can be seen ! just modification i made was just to invert the deoxyribose sugar to have antiparallel nature ! So is it just the sugars are antiparallel and bases are not ?
Legend! But there is a tiny mistake in this one sir. At 4 minutes 17 seconds you're saying that there is T in RNA when it should be a U. Were you just testing us??
