Question

Chargaff's rules of DNA structure states that
A. a+t=g+c
B.a+g=t+c
C. a=c,t=g
D. a=g, t=c
E. the number of purines in DNA never match the number of pyrimidines
i know it's not e,b, or d

Answer 1

a+g = t+c

Answer 2

B

Answer 3

why is it b

Answer 4

because in b, the ratio of purines to pyrimidines is 1:1

Answer 5

since a pairs with t and g pairs with c, you will get 50% for each side

Answer 6

ah i see cuz the book says a=t and g=c

Answer 7

yeah that's right. but a-t =/= g-c

Answer 8

that's also right. a=t and g=c because those bases pair with each other.
