Duplication of a DNA molecule is also called replication or reduction. During replication, part of the “mother” DNA molecule is decomposed into two strands using a special enzyme, and this is achieved by breaking the hydrogen bonds between complementary nitrogenous bases: adenine – thymine and guanine – cytosine. Next, the DNA polymerase enzyme adjusts the nucleotide complementary to each nucleotide of the separated DNA strands. Thus, two double-stranded DNA molecules are formed, each of which includes one chain of the “mother” molecule and one newly synthesized (“daughter”) chain. These two DNA molecules are absolutely identical.
