D. Ribonucleotide has glycosidic bond but deoxyribonucleotide do not

Answer 1

Nucleic acids are biomolecules carrying information of every living cell of every life-form on earth,They direct the process of protein synthesis and determine the inherited characteristics of every living thing.

The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

The very obvious difference between DNA and RNA is, DNA is double stranted whereas RNA is single stranted.

DNA has the bases adenine, thymine, cytosine, and guanine RNA uses adenine, uracil, cytosine, and guanine.DNA is stable under alkaline conditions, while RNA is not stable.

When the nucleotide joins the growing DNA or RNA chain, it loses two phosphate groups.So, in a chain of DNA or RNA, each nucleotide has only one phosphate group.

In both nucleic acid ,sugars deoxyribose and ribose are linked to the nitrogenous base by glycosidic linkage. It is also known as N-glycosidic bond.

So the answer is the first one ie option 'A'.
