There are two main categories of mutations.
POINT mutations only change one base and do not greatly impact the DNA sequence. These can be SILENT Substitutions, which change a base but does not change the amino acid sequence, or NON-SILENT Substitutions, which change a base AND change one amino acid in the sequence.
FRAMESHIFT mutations ADD or DELETE bases from the DNA sequence and "shifts" the entire sequence over. These can be insertions (adding bases) or deletions (deleting bases). The mutated sequence then "shifts" over because we have added or removed bases from it. Frameshift mutations have a greater impact on the protein produced because more bases are moved around than in a point mutation.

Which type of mutation has the greatest impact on the resulting amino acid sequence?

Hint: these will NOT be present in the normal icefish!!!!!
What happens to the frequency of mutations as temperature increases?
Which mutations occur most frequently as temperature increases?
The optimal temperature range that fish embryos can survive in is between .
The optimal temperature range that adult fish can survive in is between .
How are the temperature ranges between fish embryos and adult fish different?

The temperature of the water in Antarctica ranges between -2ºC in the winter to 2ºC in the summer. Climate change models have predicted that global ocean temperatures will increase by another 3.2ºC in the next 80 years. How will this affect the population of Icefish over time?
