1.If a DNA molecule has 40% Cytosine, what percent of it would be Adenine?
andrey2020 [161]

Answer:

The correct answer is -

1. Adenine - 10%

2. A-T and C-G always in DNA.

Explanation:

1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.

So, Cytosine = 40%, Guanine= 40%

total = 80%

therefore, the A and thymine would be - 100 - 80 = 20

A+T = 20

A= 10, and, T = 10%

2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.

The plant also needs to be able to release oxygen,the byproduct of photosynthesis through the stomata. The stomata are also responsible for theamount of water inside the plant. By closing when there is not enough water, the stomata prevent loss of additional water due to evaporation.</span>
