- Genes
- DNA contains genes
- sequence of DNA bases - codes for polypeptide/functional RNA
- sequence of amino acids in polypeptide forms primary structure of protein
- different polypeptides have different number & order of amino acids
- order of bases in gene determines order of amino acids
- each amino acid coded for by sequence of 3 bases in gene - triplet/codon
- to make polypeptide DNA is copied into mRNA
- 1st stage of protein synthesis
- order of bases in gene determines order of amino acids
- functional RNA is RNA molecules other than mRNA
- e.g. tRNA and rRNA
- full set of genes in cell is called genome
- full set of proteins cell able to produce is called proteome
