Youve probably heard widely varying estimates for the number of protein-coding genes in the human genome.

However many genes do not code for proteins. It is made up of 23 chromosome pairs with a total of about 3 billion DNA base pairs. Human genomes include both protein-coding DNA genes and noncoding DNA.

There are 24 distinct human chromosomes. Each list page contains 5000 human protein-coding genes sorted alphanumerically by the HGNC-approved gene symbol. Some genes are interrupted by long stretches of silent DNA for which we do not know a function.

Ie regions of the genome that are transcribed into RNA and then translated to create proteins. Go to first unread Skip to page. In order to answer the question of how many genes we have we must first agree on what we mean by the word gene.

Page 1 of 1. How many protein-coding genes does a human have. Genes stick together to make long strands of a chemical called DNA which stands for deoxyribonucleic acid.

An international research effort called the Human Genome Project which worked to determine the sequence of the human genome and identify the genes that it contains estimated that humans have between 20000 and 25000 genes. 1 Report Thread starter 11 months ago 1 Ok my so in my book it says that there are for. In humans genes vary in size from a few hundred DNA bases to more than 2 million bases.

Follow the Python code link for information about updates to the list of genes on these pages. The human genome is the genome of Homo sapiens.

While scientists have not arrived at a final number yet as of 2014 estimates suggest that the number of protein-coding genes in the human genome could be as low as 19000. Humans have about 80000 genes in their DNA.
