Question

Explain how the structure of each DNA template strand informs the structure of each newly replicated DNA strand

Answer 1

The sequence of nucleotides in the template DNA strand strictly determines the sequence of nucleotides in the replicated DNA strand. The rigor of the construction of the nucleotides of the daughter DNA strand is carried out due to the chemical complementarity of the nitrogenous bases that make up the nucleotides of the template DNA. So, according to the rule of complementarity, against the nucleotide in the template DNA chain, with a nitrogenous base adenine, DNA polymerase will always build up a nucleotide with a complementary nitrogenous base thymine in the replicating DNA. If there is a nucleotide with a nitrogenous base cytazine in the template DNA chain, DNA polymerase will always build up a nucleotide with a complementary nitrogenous base guanine in the replicating DNA.
