Question

Name the unit formed by the attachment of a base to 1' position of sugar in a nucleoside.

Answer 1

The unit formed by the attachment of a base to 1' position of sugar in a nucleoside is nucleotide.

1. They consist of bases which may be adenine, guanine, cytosine and thymine.

2.They also contain sugar in their composition.

3. At least one phosphate group must be present.

4. Nucleotides are the simple building blocks of nucleic acids like DNA .

Answer 2

Nucleotide

Explanation:

The unit formed by the attachment of a base to 1' position of sugar in a nucleoside are nucleotide units.

A nucleoside is known to be a structural component or building blocks of DNA or RNA. A nucleotide is made up of a base (adenine, thymine, guanine, and cytosine) and a molecule of sugar along with phosphoric acid. These nucleotide are made by the attachment of a base to 1’ position of sugar in a nucleoside hence the answer is nucleotide.
