Question

How can you identify the 3' from the 5' end of the DNA strand

Answer 1

Do you mean 3'\(\rightarrow\)5' \(\sf \color{red}{RNA}\) because DNA is read from 5'\(\rightarrow\) 3'

Answer 2

that is what it says on the worksheet

Answer 3

One strand is arranged in the 5' to 3' direction. In other words, it begins with a phosphate group attached to the fifth carbon of the deoxyribose -- the 5' end -- and ends where the phosphate of the next nucleotide would attach -- at the third deoxyribose carbon (3').

The adjacent strand points in the opposite (the 3' to 5') direction.

Answer 4

so u can identify each of them because one is begin with a phosphate and the other ends with a phosphate group?

Answer 5

Well, look at the position of the bond.

Answer 6

Ah, forgot the phosphate group. There shold be one there bonding them. Lol

Answer 7

:) ok got it thanks

Answer 8

I should of asked before I drew the structure, is this for basic biology or higher level biochemistry? I am not sure if you'll understand that I drew there.

Answer 9

basic biology

Answer 10

Hmm...well, that is basically what is meant. There is a phosphate group \(\sf \color{blue}{PO_4^{3-}}\) group attached there. The ribose sugar is given prime numbering. The 3' and 5' just tell you WHERE it's bonded on the sugar.

Answer 11

does it have to do with this
