Approximately 16% of this alien genome is comprised of nucleotides containing C, and 22% is comprised of nucleotides containing Y. Given this information, calculate the percentage of the alien genome that is comprised of nucleotides containing G, T, A, and X. (a) _____% of the alien genome is comprised of G. (b) _____% of the alien genome is comprised of T. (c) _____% of the alien genome is comprised of A. (d) _____% of the alien genome is comprised of X.

Answer:

(a) 16 % of the alien genome is comprised of G.

(b) 17% of the alien genome is comprised of T.

(c) 17% of the alien genome is comprised of A.

(d) 22 % of the alien genome is comprised of X.

Explanation:

Assuming the alien follows Chargaff's rules which states that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases.

So if:

16% contains C ; 16 % pairs with G = 32% C-G pairing.

22% contains Y ; 22 % pairs with X = 44% X-Y pairing.

44% G-C + 32% X-Y =  76%

100%-76% = 34% the remaining should be split between T and A which is 17% each one.
