Somatic dna
A somatic mutation is a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell other than a gamete, germ cell, or gametocyte. Unlike germline mutations, which can be passed on to the descendants of an … See more The term somatic generally refers to the cells of the body, in contrast to the reproductive (germline) cells, which give rise to the egg or sperm. For example, in mammals, somatic cells make up all the internal organs, skin, … See more As with germline mutations, mutations in somatic cells may arise due to endogenous factors, including errors during See more Somatic mutations accumulate within an organism's cells as it ages and with each round of cell division; the role of somatic mutations in the development of cancer is well established, and is implicated in the biology of aging. Mutations in neuronal See more Research suggests that the frequency of mutations is generally higher in somatic cells than in cells of the germline; furthermore, there … See more • Mosaic (genetics) • Human somatic variation See more WebSep 23, 2024 · The article by Su et al 1 documents an interesting example of somatic cell evolution, where a deleterious germline heteroplasmic mitochondrial mutation is frequently lost in mitotic intestinal epithelium but not in adjacent smooth muscle cells. Essentially the epithelium ‘improves’ with age as mutant mitochondrial genomes are purged. Somatic cell …

Various mutations in oncogenes, tumor suppressor genes, and DNA repair mechanisms … Like all cells, somatic cells contain DNA arranged in chromosomes. If a somatic cell contains chromosomes arranged in pairs, it is called diploid and the organism is called a diploid organism. The gametes of diploid organisms contain only single unpaired chromosomes and are called haploid. Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. In humans, somatic cells contain 46 chromosomes organized int…
