Explanation / Answer

Answers:-

11:- d) A & B above

Explanation:- Triacylgycerol is made up of one glycerol molecule and three fatty acids. They are held together by ester bond. So option d) is correct.

12:- a) Phosphoglycerides

Explanation:- Major class of lipids found in mammalian cell membrane is phospholipid which is composed of phosphoglycerides and sphingomyelins. So phosphoglycerides is correct option.

13:- b) Synthesis of DNA

Explanation:- Deoxyribonucleotide is composed of 3 components : Deoxyribose sugar, phosphate group and nitrogenous base ( A, T, G & C ). These three components make a unit of DNA. So option b) is correct answer.

14:- c) 5' CTGTATGGGTCTGCCATATAACT 3'

Explanation:- Because A binds with T and C binds with G and vice versa. So option c) is correct answer.

15:- c) 10.4

Explanation:- B form of DNA has about 10 - 10.5 base pairs per turn. So option c) is correct answer.
