• A. adenine
• B. deoxyadenylic acid
• C. adenosine
• D. deoxyuridine phosphate

Answer 1

Answer: (B)

DNA is a polymer of nucleotides which comprises nitrogen base (A, G, T, C), sugar (dexyribose) and phosphoric acid the four types of nucleotides present in DNA as follows.

Deoxynucleoside $+H_{3}P{O}_4$	Deoxyribonucleotide	Abbreviation
Deoxyadenosine + $H_{3}P{O}_4$	Deoxyadenylic acid	d- AMP
Deoxyguanosine + $H_{3}P{O}_4$	Deoxyguanylic acid	d - GMP
Deoxycytidine + $H_{3}P{O}_4$	Deoxycytidylic acid	d- CMP
Deoxy thymidine + $H_{3}P{O}_4$	Deoxythymidylic acid	d- TMP
