Detailed explanation-1: -Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
Detailed explanation-2: -The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
Detailed explanation-3: -The copies of DNA synthesised by PCR are not identical and each copy formed has certain variations.
Detailed explanation-4: -If the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original.
Detailed explanation-5: -During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or “old” strand. Each new double strand consists of one parental strand and one new daughter strand.
