A mutation can have3 effects. What are they?

Answer 1

1) it may help the organism survive better
2) it may prevent the organism from surviving as well
3) it may cause death before the organism reaches maturity.

Answer 2

1- It can delete a part of the genetic code, shifting everything over, so a stop codon (let's say its UUU, I can't remember) that worked in the ATG UUU sequence would be misread if something was deleted: AGU UU? <-- 3/4 chance there's no stop codon now
2- It can change the base. This can lead to beneficial, harmful or no effect.
3- It can add a base, and the same effect for deletion would occur.

Answer 3

1. beneficial to the individual
2. harmful to the individual
3. no effect
