Mutations that occur at random are called spontaneous mutations.
Interphase
There is no definite answer to this question many types of mutations can cause death and I'd say that's the most dangerous effect of a mutation. Large Scale mutations, like deletions or amplifications, usually cause the most damage because they effect whole chromosomes. Small Scale mutations are usually less dangerous because they only effect one gene. The worst small scale mutations are insertions and deletions because they change the reading frame. In my personal opinion, harmful mutations that occur in the tumor suppressor genes are the most dangerous because they are what prevent the mutations in cell from being duplicated and without them working a mutated cell can replicate uncontrollably.
Mutations that occur at one single nitrogen base are referred to as a point mutation.
Such mutations are called point mutation or gene mutation.
Mutations happen in ALL living things (and also in viruses)!!!!!!
Somatic mutations are not passed on to offspring because they occur in non-reproductive cells. These mutations only affect the individual in which they occur, and are not transmitted to future generations.
Gene mutations that occur at a single point in the DNA sequence are called point mutations. These mutations can involve substitutions of one nucleotide for another (missense mutation), insertion of an extra nucleotide (insertion mutation), or deletion of a nucleotide (deletion mutation). Point mutations can have various effects on the resulting protein, ranging from no impact to severe functional changes.
Mutations that occur in DNA
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
Cis mutations occur on the same strand of DNA, while trans mutations occur on different strands. Cis mutations affect nearby genes, while trans mutations can affect genes located far apart.
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
