What is the difference between a ribonucleotide and a deoxyribonucleotide?
a. ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit.
b. ribonucleotides contain a phosphate group.
c. ribonucleotides have a hydrogen atom on the 1 carbon of their sugar sub-unit.
d. ribonucleotides contain a sugar with five carbon atoms.

The difference between a ribonucleotide and a deoxyribonucleotide is: a. Ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit.

Ribonucleotides is the basic unit of a ribonucleic acid (RNA). It basically comprises a phosphate group and a nitrogenous base that is referred to as ribose sugar. Also, its nitrogenous base includes the following components:

On the other hand, deoxyribonucleotides is the basic unit of a deoxyribonucleic acid (DNA). It basically comprises a nitrogenous base and phosphate group that is referred to as deoxyribose sugar. Also, its nitrogenous base includes the following components:

Hence, the pentose sugar component (ribose and deoxyribose sugar) is one of the differences between a ribonucleotide and a deoxyribonucleotide.

Generally, the molecule which is found on the 2 carbons of ribonucleotides is a hydroxyl group (OH atom) while deoxyribonucleotides have a hydrogen atom (H atom) on the 2 carbons of their sugar subunit.

The answer to your question is: letter A

Explanation:

a. Ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit.  This is the main difference between Ribonucleotides and deoxyribonucleotides, the first have hydroxyl group in carbon number two, while the second have a hydrogen.

b. Ribonucleotides contain a phosphate group.

c. Ribonucleotides have a hydrogen atom on the 1 carbon of their sugar sub-unit.

d. Ribonucleotides contain a sugar with five carbon atoms.

you gotta add the following molecules so we can give u an answer
