How can a mutation occur?

Question

A mutation is a change in the nucleotide sequence of a DNA molecule. How can it occur?

Answer 1

There are many ways that a mutation can occur, any "mutagen" (a "substance" the can potentially mutate your DNA sequence) can technically cause changes in your nucleotide sequence.



Meiosis and mitosis of the cells are NOT perfect mechanisms and mutations do occur in the cells without being fixed sometimes.

U.V radiation/X-rays

Some chemicals if working in a lab.

Through actually adding in a new nucleotide sequence (common studies done in yeast).



If you want a more extensive list, type the word "mutagen" on google and it should give you examples of such.

Answer 2

a mutation can occur if the base on the DNA is removed, replaced, or changed. If a base is removed it can cause a serious mutation. The sequence will be shortened and no protein will be made. If it's replaced the whole sequence will change and produce a different or sometimes no protein. If its changed then it can cause the production of proteins to immediately stop, which can be a problem for the person. If its change with another it can cause another protein to be produced or abruptly stop during protein synthesis.

Answer 3

A mutation occurs from a cells DNA being altered. Also is hereditary.
