If a specimen contains 30% adenine in its dna, how much cytosine will it contain? 40% 30% 20% 10% 15%

The specimen will contain 20% cytosine in it's DNA.

COMPONENTS OF DNA:

Since G = C and A = T

G + C + A + T = 100%

G + C + 30 + 30 = 100

G + C = 100 - 60

G + C = 40%

G/C = 40/2 = 20%

Therefore, G or C will be 20% each. Hence, the specimen will contain 20% cytosine in it's DNA.

the correct answer is b

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
