In a mutational event,when adenine is replaced by guanine,it is called:

Identify the following point mutations in $mRNA$: $UAU\ ACC\ UAU$ to $UAU\ AAC\ CUA$ and $UUG\ CUA\ AUA$ to $UUG\ CUG\ AUA$.

$...$ is a phenomenon by which genetic variation is achieved through changes in the base sequences within genes,which creates a new character or trait absent in the parental generation.

Mutations that involve a single base substitution are induced by .......

The chromosome shown in the diagram below is broken at the points which are indicated by the arrows and the genes between these points become inverted. The resulting order of the genes will be:

Mutations are responsible for
