Question

4. A DNA molecule has 200 Adenine and 400 Guanine, therefore the total number of nitrogenous bases
in this DNA is
600
800
1200
1600​

Answer 1

Answer:

The answer is 1200 nitrogenous bases.

Explanation:

Number of Adenine: 200

Number of Guanine:

$\mapsto$ We know that Adenine always binds with Thymine and Guanine always binds with cytosine.

So,

Number of Thymine: 200

Number of Cytosine: 400

Total = 200 + 200 +400 +400 = 1200

Answer 2

Answer:

the total number of nitrogenous bases is 1200

Explanation:

Adenine binds to Thymine 200+200=400

guanine binds with cytosine 400+400=800

thus, 800+400=1200
