Sudden heritable change in the nucleotide sequence of DNA.

Mutation is a sudden inheritable change in the nucleus sequence of DNA in a organism.

…………………mutation is the changes occuring in nucleotide sequence of a gene.

During transcription, the nucleotide sequence of the DNA stand that is being coded is ATACG, then the nucleotide sequence in the mRNA would be

During transcription, if the nucleotide sequence of the DNA strand that is being coded is ATACG, then the nucleotide sequence in the m RNA would be

During transcription, if the nucleotide sequence of the DNA strand that is being coded is ATACG, then the nucleotide sequence in the m RNA would be

During transcription, if the nucleotide sequence of the DNA strand that is being coded is ATACG, then the nucleotide sequence in the m RNA would be

When there is change in the base sequence of DNA it is called as
