In a broad technical context, genes are a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell (or virus) may synthesize.

Put in a simple way: Genes are made of DNA that contains information in coded form.

When genes are active, instructions are decoded and expressed in the phenotype.

There's some great information out there about genes (and other important VCE Biology concepts) on Mr. Barlow's VCE Biology podcast which is definitely worth listen: https://itunes.apple.com/au/podcast/vce-biology/id272577510
