Defects during cell division can result in cells containing either too few or too many chromosomes, which are molecules of DNA.
Web29 okt. 2024 · Mitosis occurs whenever more cells are needed. It happens throughout the entire lifespan of a living organism (human, animal or plant) but most rapidly during periods of growth. This means, in humans, the fastest rate of mitosis happens in the zygote, embryo and infant stage. WebCalvin Bridges and Thomas Hunt Morgan discovered the process of nondisjunction in dividing cells in the year 1910. This is one of the most common forms of chromosomal aberration that occurs in humans. This BiologyWise post explains what is nondisjunction, how does it occur, and some of the causes and effects of this condition.
