gene mutation,
chromosomal abberations
i] spontaneous mutation ii] induced mutation iii] germinal mutation iv] somatic mutation v] chromosomal mutation vi] gene mutation are the some of the major types of mutation......
nonsense mutation, missense mutation, frameshift muation, deletion or addition mutation
From another angle: beneficial and detrimental.
An insertion/deletion event.
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
insertion and deletion
Frameshift
When the APC gene is mutated, it disrupts the normal regulation of cell growth and division in the colon. APC normally acts as a tumor suppressor, helping to control the Wnt signaling pathway, which is crucial for maintaining proper cell function. A mutation can lead to uncontrolled cell proliferation, contributing to the development of benign polyps and, ultimately, colorectal cancer. This mutation is a key early event in the progression of certain types of colon cancer.
a major event is something very big that has happened
A major event is that man walked on the moon. Another major event is that President Kennedy was shot. Another major event was the bombing of Pearl harbor.
I think that Hitler's major event was the killing of the Jews.
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
