All mutations to the base sequence of DNA are harmful true or false?

false. some mutagens increase the orgamisms fitness, other decrease it . other make the organism not viable


so it all depends on what tht mutation changes comppared to the enviromentAll mutations to the base sequence of DNA are harmful true or false?
False, the mutation may prove to be advantageous, or, may not cause any problem at all, this is because a amino acid can be coded for by more than one codon (group of bases) eg, TTT and TTC both code for Phenylalanine, therefore a change in this base would have no effect whatsoever on the final protein.All mutations to the base sequence of DNA are harmful true or false?
False.


Mutations are the way we get variation, and if those mutations prove valuable, then they survive better than what was there before, and eventually become the norm until another mutation arises that is better.
