"Comparison of conserved sequences among related species usually leads to the identification of sequences, which illustrate the nucleotides most often found at each position of DNA in the conserved region."

Explanation:

Such type of the nucleotide sequence that is mostly present at each position is called a consensus sequence. This sequence plays an important role in the sequence alignment and some other molecular biological research and some other fields. Generally, it is made up of a small segment of the nucleotide and also considered as a conserved sequence motif because its presence is conserved on the position where it is present.
