Sentences with phrase «single nucleotide»
A "single nucleotide" refers to a small building block of DNA or RNA. It is like a single letter or code that makes up the genetic information in living organisms. Just as letters combine to form words, single nucleotides combine to create genetic instructions for cells. Full definition
