Gene

Genes are segments of DNA or RNA which are transmitted through generations, and contain genetic information useful for building the sequence of amino acids to make a protein. Genes are found in the chromosomes, located in the nucleus of the cell.
Another way to define a gene is as a segment of DNA which codes for a polypeptide (and thus a protein).
The information is copied from the DNA to the mRNA (messenger RNA) with the help of some enzymes. This messenger then goes outside the nucleus and goes to the ribosome. There, the protein is built along with tRNA (Transfer RNA) and rRNA (ribosomal RNA). The protein is finally built by the rRNA, which assembles each amino acid until the full protein is complete.
