(v)	Uracil

Which of the following is the best matched option?

• A. i- AD ii - B, iii - C, iv - B, v - A
• B. i- AD, ii- C, iii - A, iv - BC, v - B
• C. i- A, ii - CD, iii - A, iv - B, v - C
• D. i- D, ii- BC, iii - B, iv - B, v - A

Answer 1

The correct option is B i- AD, ii- C, iii - A, iv - BC, v - B

Amino acids form proteins and exist as zwitter ion.
Thymine is a nitrogenous base in $DNA$.
Insuline is a protein.
Phosphodiester linkage is found in nucleic acids and also in $DNA$.
Uracil is nitrogenous base found in $RNA$ which is a nucleic acid.
