Why is the order of amino acids so important?

The order of amino acids dictates what shape the protein will fold into.

It is not important. The protein folding chamber will force the protein to fold into the correct shape.

Why does DNA replication have to occur?

So that it can fix any mistakes the cell made during division

So that the cell can get bigger

So that each new cell will have a exact duplicate copy of chromosomes after mitosis

So that each cell has a back-up copy of its DNA

Would a mutation in the DNA of a skin cell be passed on to an organism's offspring?

Yes, because any change to the DNA is passed on to the offspring

Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated.

No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring

Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.

Why are insertion and deletion mutations so harmful?

They change all of the codons (amino acids) from the mutation on down the line, which changes the amino acid sequence

They insert things that an organism doesn't need.

They often delete things that organisms need.

Insertion and deletions are not any more harmful than substitution mutations.
