Question

Select the correct option:

The three structural formulae A, B and C are given here. Identify them and select the correct option.

• A. Adenine(N-base), Adenosine (Nucleotide), Adenylicacid (Nucleoside)
• B. Adenine(N-base), Adenosine(Nucleoside), Adenylicacid (Nucleotide)
• C. Adeposine (Nucleoside), Adenylic acid (Nucleotide), Adenine (N-base)
• D. Adenosine (Nucleoside), Adenylic acid (Nucleotide), Deoxyadenylic acid

Answer 1

Answer: (B)

Adenine(N-base), Adenosine(Nucleoside), Adenylicacid (Nucleotide)

Basic components of the genetic material are the nucleic acids.

Structurally and nucleoside is a combination of a base or sugar and phosphate group and a nucleoside is nitrogenous base + pentose sugar.

Here we can see that this is a purine which is a nine-member, doubled ringed nitrogenous base and when ribose sugar is added it forms the nucleoside adenosine. Again when adding phosphoric acid it gets converted into adenylic acid which is a nucleoside.

So, the correct option is 'Adenine(N-base), Adenosine(Nucleoside), Adenylicacid (Nucleotide)'
