HII! I really need help on these questions! 1) how does a mutation affect the expression of a gene or the sequence of amino acids in a protein.

2)how does mutations cause changes in organisms?

3) are mutations good or bad? Explain your answer.

4) why is it unlikely that we would have mutations that create people like the X men or Incredible Hulk?

a mutation is a change in the base sequence of DNA, the substitution of the sequence of amino acid in the resulting protein may also be altered. mutation most commonly error in the replication process.the effects such as problem in development or can lead to variety of genetic disorders.Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.Effects of MutationsA single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious.one thing is that we just dont know enough about the 'genetic potential of our genes' to produce superhuman abilities like the xmen and hulkwe're all technically mutants, but mutating like the xmen would probably get us killed bc of how drastic of a physical change it is.alsoo if everyone had a mutation like the xmen/hulk, all the mutations wouldnt be similar enough for people to breed meaning that eventually, over a long long time humans/mutants would become extinct possibly.its pretty unlikely that we would be able to change that much physically without ruining our likelihood of reproducing.
