You taught me more than one full semester of biology at my highschool. Thank you so much ❤️ You are a hero!!

U r one of best teacher unfortunately I never had till today......

Sir you are such a such a prolific teacher .

Wow! You are such a good teacher!

you are an amazing teacher I used to worry about my biology

You are a wonderful teacher

you generous person thank you for this leason

Please I have a question. I thought ligase was the glue and DNA polymerase did the actual building

Nice and clear videos! I have question, what is biochemical process of unzipping? What kind of structural modification is there? Is there some reports and study?

Thank you for the videos.I like the way you explained the information

My only complaint is that the video is a little bit quiet and thus kind of hard for me to hear.

Mutations can be corrected.. okay.. but.. how to know which side is the "bad" part?

Absolutely excellent.

You are the best 😊

Hi there, can I have a question, since RNA is the copy of DNA, why it has different nitrogen bases? Based on my limited understanding, copy means exactly the same. Thank you for your time to make the wonderful videos!

Love all the biology videos you made and it is very helpful, thank you so much!

thanks, You are awesome!
