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… simplyhealth group ltd

WebApr 16, 2024 · Spontaneous accumulation of somatic DNA mutations has been hypothesized as a cause of both cancer and aging. However, detecting mutations in normal, noncancer cells is challenging, because mutations accumulate independently in each cell. WebOct 4, 1991 · A DNA construct containing the bacterial β-galactosidase gene ( lacZ) was used to study somatic DNA recombination in the transgenic mouse brain. Recombination-positive areas of the adult brain were stained blue with X-gal, a substrate of β-galactosidase. Blue-colored cells appeared soon after birth, and continued to emerge in postnatal tissue.
