•List of human protein-coding genes page 4 covers genes SLC17A8–ZZZ3 NB: Each list page contains 5000 human protein-coding genes, sorted alphanumerically by the HGNC-approved gene symbol. Follow the Python code link for information about updates to the list of genes on these pages.
Although silencing of some genes in cancers occurs by mutation, a large proportion of carcinogenic gene silencing is a result of altered DNA methylation (see DNA methylation in cancer). DNA methylation causing silencing in cancer typically occurs at multiple CpG sites in the CpG islands that are present in the promoters of protein coding genes.
Unlike prokaryotes where exon-intron organization of protein coding genes exists but is rather exceptional, eukaryotes generally have these features in their genes and their genomes contain variable amounts of repetitive DNA. In mammals and plants, the majority of the genome is composed of repetitive DNA. [31]

The human reference genome contains somewhere between 19,000 and 20,000 protein-coding genes. [14] [15] These genes contain an average of 10 introns and the average size of an intron is about 6 kb (6,000 bp). [16] This means that the average size of a protein-coding gene is about 62 kb and these genes take up about 40% of the genome. [17]
The smallest genomes occur in viruses, [95] and viroids (which act as a single non-coding RNA gene). [96] Conversely, plants can have extremely large genomes, [97] with rice containing >46,000 protein-coding genes. [91] The total number of protein-coding genes (the Earth's proteome) is estimated to be 5 million sequences. [98]
He named this DNA–protein interaction (the original genetic code) as the "diamond code". [5] In 1954, Gamow created an informal scientific organisation the RNA Tie Club, as suggested by Watson, for scientists of different persuasions who were interested in how proteins were synthesised from genes. However, the club could have only 20 ...
The coding region of a gene, also known as the coding DNA sequence (CDS), is the portion of a gene's DNA or RNA that codes for a protein. [1] Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene ...
