They can also appear spontaneously during the replication of DNA. Mutations generally fall into two types: point mutations and chromosomal aberrations. In point mutations, one base pair is changed.

Gene mutations have consequences both good and bad—from resistance to conditions like diabetes to susceptibility to certain cancers. In order to study these mutations, scientists need to ...

There are many different types of mutations which can arise in DNA. This diagram shows the normal order of the bases for one of the strands in a DNA molecule. Only one of the strands of DNA is ...

All cancer mutations that cause drug resistance fall into one of four categories. New research has detailed each type, helping to uncover targets for drug development and identify potential ...

To date, around 50 different type of mutations (changes) have been identified throughout the AIP gene, causing the development of a pituitary adenoma. The majority of the mutations change the ...
