What is sequential mutation?

Answer 1

It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.

Answer 2

Sequential mutation refers to the process where mutations occur one after the other in an orderly sequence within a gene or genetic pathway. This can lead to accumulative changes in the DNA sequence, potentially resulting in altered gene function or disease development.
