Chromosome 4 (human)

from Wikipedia, the free encyclopedia
Human chromosome 4 idiogram

Chromosome 4 is one of 23 chromosomes pairs of people . A healthy person has two largely identical copies of this chromosome in most of his cells .

Decoding the chromosome 4

Chromosome 4 consists of 191 million base pairs . A base pair is the smallest unit of information in DNA . Chromosome 4 contains approximately 6% of the total DNA in a human cell . Identifying the genes on this chromosome is part of an ongoing process of deciphering the human genome. There are between 700 and 1200 genes on chromosome 4. The sequencing in April 2005 found 796 protein-coding genes and 778 pseudo-genes . Pseudo-genes are no longer functional ("switched off") genes. The proportion of pseudo-genes on chromosome 4 is extremely high at almost 50%.
