A = G
|
|
|
A + G = C + T
|
|
|
A + T = G + G
|
|
|
A = C
|
Detailed explanation-1: -A+G=C+T shows the exact base pairings of the DNA. The amount of adenine and guanine equalizes the amount of cytosine and thymine. According to the base-pairing rule, the number of bases present in the DNA sample balances the number of bases such as A and G, C and T. Therefore, the given statement is true.
Detailed explanation-2: -Bases pair up with each other in a consistent way, and this process is called complementary base pairing, or Watson-Crick base pairing. This consistent pairing of bases allows DNA to accurately replicate itself. It also allows DNA to be transcribed accurately into RNA and then translated from RNA to amino acids.
Detailed explanation-3: -Chargaff’s rules state that in the DNA of any species and any organism, the amount of guanine should be equal to the amount of cytosine and the amount of adenine should be equal to the amount of thymine.
