How Many Genes Does A Human Being Have?

The human has about 200 000 different genes. The genes are arranged on separate, very long pieces of DNA, each one of which is wound up to form a chromosome. Humans have 46 chromosomes in total – 23 pairs. One of each pair is passed down from your mother, one of each pair is passed down from your father. This means you have two copies of every gene – these different copies are called alleles.

A gene is a section of deoxyribonucleic acid that codes for a functional protein. Every living organism has a large collection of genes, each one coding for the production of a different protein.

When a gene is expressed to produce a protein, the chromosome has to be unwound so that the protein making template can be made. The DNA untangles and then the DNA double helix itself unwinds so that an RNA (ribonucleic acid) copy can be made. This messenger RNA acts as a template and passes out of the nucleus to the ribosomes, the protein making machines in the cell.

The count of genes in a human being is between 20,000 to 25,000 genes. There are less then 3 billion base pairs. The total genes in an organism will be called genome. The density of genome is the number of genes per one million base pairs. So, the number of genes in a human genome is 20,000-25,000. The Human Genome project has had a great influence in determining the number of genes in a human body. This project was completed in 2005. The genome in every individual (human or not) is unique. Except identical twins who have similar or almost similar genomes, that makes them look alike. Human Genome project was undertaken by a privately owned company called Celera Genomics in 1998. Since, many other companies have shown interest in the development and research related to research in this area. Some of the other projects are International Hap Map Project, Personal Genome Project and Perlegen.

About 200000

20,000 - 25,000

There are over 30,000 genes in the human body.

200,000

There are 200,000 genes in the human body.

I don't no, y the hell should I tell you anyway? Go crack a book open and get a life!

46 genes, and there are 23 pairs of them

Well each person gets 23% of genes each from their Mother & Father which means you have 46% of genes all together

You all suck at this there are many genes and like dominant alleles and recessive ones lol sorry I have no idea what I'm saying right now :) bi
