RNA, like DNA, is a nucleic acid or polymer of nucleotides. The nitrogenous base uracil is found in place of thymine. The linear sequence of nucleotides in DNA ultimately determines the linear sequence of amino acids in a protein. Nucleic acids are made of four types of nucleotides which differ in their nitrogenous bases. Hundreds or thousands of nucleotides long, each gene has a specific linear sequence of the four possible bases.
Information flows from gene to protein through two major processes, transcription and translation .
