Question

The difference between DNA and RNA is in the

A) sugar ring
B) adenine
C) phosphate group
D) phospholipid group

Answer 1

The difference between DNA and RNA is in the sugar ring.

Step-by-step explanation:

In case of the DNA it is the deoxyribose, while in RNA it is ribose sugar. Deoxyribose is modified form of sugar with absence of the one oxygen atom hence named ‘deoxy’. The absence of 1 oxygen is important because it helps the enzyme to differentiate between DNA and RNA.

While in ribose sugar, each atom is attached with one oxygen atom. There is a hydroxyl group present in the RNA that helps in RNA splicing. But in the deoxyribose the hydroxyl group is replaced by the hydrogen atom.

Answer 2

The correct answer is A) sugar ring. See the explanation below, please

Step-by-step explanation:

The DNA has sugar deoxyribose and RNA ribose. Another difference between the two may be the following: in DNA, Adenine is paired with Thymine and in RNA with uracil.
