Genes in human Genomes

The human genome is just over 3 billion base pairs of DNA that codes for a 750 MB 20000-25000 information and protein-coding genes. This is much smaller than the original estimate of 100,000 or more. The number of human genes appear to be the human genome project was completed in 2003. Although the goal of sequencing the human genome, a second important task for the project to the number of genes to determine their positions and give an idea of the operation.

Genes are long stráicí of DNA, which is the smallest unit of heredity. Variations of genes used as allele. For example, believed that requires at least a couple of the gene for human hair, and depending on the composition of the alleles that a person has black hair, brown hair, red hair, blond hair, or other variations in between.Because the process is a complex gene expression, we have much to learn before we can see that all 20,000 + genes in the data and how each character is associated with human genetics.
The human genome is only twice the genes of animals is much easier, and roundworms (nematode) or fruit fly. Yes, a small correlation between complexity and the number of animal genes. It is assumed that a greater differentiation in human biochemistry scuffles with the results that our genes and implies that the EU, like a number of proteins synthesized from a gene. In its simplest form, composes only one gene for the protein.

Because we will analyze the human genome, we can eliminate or hypothetical genes, and narrow, the actual genes that may even be less than 20,000. Genes have multiple functions in the human body and mind, including size, tendency to depression, a tendency to overweight together, cardiovascular diseases, hereditary disease, the data in the presence or absence of freckles, and more. Because the genome was time to face, but lately, it is still much work to figure out what to do each of the genes.
