Question

: If a DNA molecule has 2000 bp then calculate the,
(a) Number of sugar and phosphate molecules
(b) Number of N-glycosidic linkage​

Answer 1

Answer:

a) 4000

b) 4000

Explanation:

Each base pair of DNA has two pentose sugars and phosphate molecules and two glycosidic linkages as DNA is double stranded structure.

Answer 2

Answer:

(a)  4000

(b)  4000

Explanation:

A DNA molecule of 2000 BP means it has 2000 bases on each strand, that is 4000 based on the two strands together. Each of these bases is connected to a sugar and each sugar is connected to one phosphate group. So total 4000 base, 4000 sugar, and 4000 phosphate molecules are present.

So the correct answer is '4000 sugar and 4000 phosphate molecules'.
