The number of the dorminat alleles varies with the genotyoe. In addition, the factors as mutation also contribute to the mutation of the genes. The mutation in the DNA causes a different set of instruction in the DNA. This then affects the gene expression in an organism.
Answer:GGATCGA
Explanation:
The complementary double helix of the DNA are antipararell to each other.
Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).
Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below
5' CCTAGCT 3'
3' GGATCGA 5'
