Nucleic acids

Question

In the structure of nucleic acids, A phosphodiester linkage is formed between ----- and ------- positions of ribose sugar moities

Moderate

A

$1^{'} and 5^{'}$
B

$5^{'} and 3^{'}$
C

$1^{'} and 3^{'}$
D

$2^{'} and 5^{'}$

Solution

One of the sugar moiety involves its $5^{th} - {CH}_{2} OH$ group to condense with a -OH group of phosphoric acid;
The other -OH group of the same phosphoric acid molecule condenses with $3^{rd}$ -OH group of the other sugar moiety;
Thus a phosphodiester linkage devoleps between $5^{'} and 3^{'}$ carbon atoms of two sugar moities;
