Question

1.A DNA coil has 26 hydrogen bonds. What is the percentage of thymine in that coil ? A 15% B 20% c 30% d 40 % 2. a dihybrid cross made between two pea plants one having green pods with green seeds and yellow pods with yellow seeds . 640 plants are produced in F2 generation . How many plants are expected having green pods with yellow seeds

Answer 1

Explanation:

for first question answer is 20/

Answer 2

Answer:

Explanation:

First Question's ans

1 coil=10 bp = 20 base

Let x be either adenine or thymine (both are equal in no. And form double bond)

10-x be either cytosine or guanosine ( both equal in no. And form triple bond)

Put it in a equation

X×2 + 3×(10-x) =26

On solving x=4

Calculating ――>4×100/20=20%
