5' 3' ends of DNA and RNA

Показать описание

This video will explain the two different ends of DNA - the 3' and 5' ends. How these ends are labeled, how to identify them in molecular pictures, and their significance will all be described.

Thank you so much!!! I was lost and confused until now, but now I am confident I will pass my biology exam.🥰

this helped me so much😭 I've been searching for half an hours and some other videos cant get me understand but this video is really easy to understand! tysm🥺

Thanks a lot, at my school they keep mentioning 3' and 5' and the directions but I had no clue what that actually meant, your video makes clear sense!

alexaghajanov

This is the first time this concept has made sense to me. Thank you so much!

ayyylien

Ahh, makes so much more sense! A very articulate and well done explanation. Thank you so much.

1:06 You mentioned that there is a hydroxyl group on 3' but you didnt mention the one on 2' that is shown in the diagram. Is there definitely a OH group on the 2' and does it have a function?

glennrossdolan

Sir first of all Thank you!
Can u answer my one doubt?
In transcription which strand of DNA is used??
Is it continuous strand / leading strand ?

proudindian

Hey dude your Hydroxyl group in the first diagram for 3 prime is in the wrong spot :/// you put it in 2 prime

cabinjackalope

Why always chain grow from 3 prime Why not from 5 prime Tell me reason

hamzafaryad

Not clear on this - is there an OH group at each 3' position, or only at the end of a string of bases? Thanks

Great Video! (Jesimiel Millar Fernåndez) 1M1K4

Wow... so that's why its called 5' or 3'.... its based on the carbon on the pentose molecule

brandonodedina

you have the wrong picture of DNA nucleotide.
your picture looks like the 3 carbon is deoxygenated and 2 carbon has the hydroxyl.
polymerization occurs from the 3 prime carbon.
please fix and re submit
