You discover a new organism and analyze its DNA. If you find 40% of nucleotides are G, which of the following is true: 20% are A 10% are A 20% are C 10% are C

10% are A

Explanation:

according to charghaffs rule there is always equality in quantity between A and T bases and G and C bases in DNA.

T = thymine

A = adenine

G = guanine

c = cytosine

from this the molar ratio of a to t is 1 and g,c = 1

G = 40%

so cytosine = 40%

sum of pusine and pyrimidine = 100%

(a+g) + (t+g) = 100%

(a + 40) + (t + 40) = 100%

a+t +80 = 100%

a + t = 100-80

a + t = 20%

a = t, t = a

2a = 20%

a = 20/2

A = 10%

your answer is "the 1950's"

i think its white blood cells

i hope this
