Answer:E. coli: Cytosine- 26, Thymine-24
Human: Guanine-20, Cytosine-20
Ox: Guanine-21, Cytosine-21, Thymine-29
Explanation:
Chargaff's rules state that in a given DNA molecule the percentage of Adenine %A is approximately equals the percentage of Thymine %T and the percentage of Guanine %G is approximately equals the percentage of Cytosine %C.
Answer is
E. coli: Cytosine- 26, Thymine-24
Human: Guanine-20, Cytosine-20
Ox: Guanine-21, Cytosine-21, Thymine-29
