(B) 120
(C) 150
(D) 200​

Answer 1

Answer:

150 uset how many new clips are present at 70° length of DNA

Answer 2

Answer:

Here the concept of nucleotides and base pair is used. Each base pair has two nucleotides.

Given:

We have length of DNA = 170 $A^{0}$

Find:

Each base pairs occupies the length of 3.4 $A^{0}$.

Solution:

As we know that each base pair has two nucleotides and each base pairs occupies the length of 3.4 $A^{0}$.

Therefore, base pairs present in 170 $A^{0}$ = 170 / 3.4

                                                                  = 50

Hence, the total number of nucleotides= 50*2 = 100.
