Answer:
During the process of replication, the double stranded DNA separates when several enzymes act to break the bond between base pairs in two strands.
There are four base pairs in DNA that includes thymine, cytosine, guanine and adenine. these bases determines DNA's instructions, or genetic code. The four bases are allowed to encode the sequence of amino acid residues in proteins by making a pair of three codons that carry genetic codes and helps on the process of transcription and translation.
For example: if the DNA sequence is having bases ATGCCGG, its complementary base pair will be UACGGCC, lets make pair of three codons UAC that codes for amino acid Tyrine and GGC codes for glycine.
Bases are components of nucleotide and nucleotide are the basic building blocks of DNA and RNA.
If DNA will separate from any other point then it will not able to carry the genetic code. hence, DNA separates between the bases only.
