People with diseases caused by rare mutations have fewer options and poorer prospects than other patients despite rapid ...

Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the ...

In point mutations, one base pair is changed. The human genome, for example, contains over 3.1 billion bases of DNA, and each base must be faithfully replicated for cell division to occur.

Rather than causing instability, some missense mutations led to different changes in proteins. For example, some of the mutations behind Rett syndrome, a rare neurodevelopmental disorder ...

Nonetheless, certain other mutations can greatly impact the life and function of an organism. For example, somatic mutations that affect cell division (particularly those that allow cells 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 ...

Mutations could cause different genes to be switched on or off, and this could create a different or faulty protein to be synthesised. For example, if the protein is an important enzyme ...
