The percentage of cytosine bases in the molecule is?
please show me how you work this out. I am struggling in these type of question.

30% T
30% A
70% G
70 % C
(48/160)/100= A

well there's 160 bases right? and for every thymine there's adenine so subtract 96 (48*2) from 160 wich equals 64cytosines and guanine (devide by two cuz you only want cytosines) and you'll have 32 cytsines...now just find the % :)
for the %, you just take 32/160 (should give you .2) and then multiply by 100 (gives you the final answer of 20%)

Chargaff's rules state that the equivalences for any given species between the number of A and T bases and the number of G and C bases are:
-A = 30.3%
-T = 30.3%
-G = 19.5%
-C = 19.9%
The percentages refer to the 4 bases in human DNA.
