Many were confused by the differences between channel proteins (passive) and protein pumps (active).Recent researches have verified the basic conclusion about gene-enzyme relationship. Currently the Beadle and Tatum’s concept of one gene-one enzyme has been revised to one gene-one polypeptide chain (protein) in view of the complexity in the structures and the functions of enzymes.
The gene can be read(via transcription and translation) from an ATG codon. As there are two ATG codons(bolded) in the above code, this can(potentially) code for two polypeptides, each with their code shifted one base along. This can theoretically be increased to three polypeptides on one gene.Genes are DNA sequences that code for a protein. When genes are to be expressed by a cell they need to be copied and the non-coding parts edited out before they can be turned into protein. This process is called RNA splicing.
