Chargaff’s rule states that the amount of _______ in DNA is always roughly equal to the amount of thymine, and that the amount of guanine in DNA is always roughly equal to the amount of cytosine.
List the DNA bases that will complementary base pair with the following sequence:
A-G-C-T-A-C-G
Nucleic acids such as DNA are polymers of
nucleotides. Each nucleotide consists of a
five-carbon sugar bonded to a nitrogen
base and a phosphate molecule. Each
carbon on the sugar is numbered with
primes according to chemical convention.
