Review for Science Test
 How does this strand of DNA become a protein
 ATGCGTCTGGCAA
 Transcription (DNA – RNA) – In the Nucleus
 Translation (RNA – Protein) – In the cytoplasm
 What would happen if the sequence of letters mutated:
 Changed one letter
 Deleted letters
 Rearranged letters
 Mutations change the order of the letters resulting in different amino
acid sequences (translation) which results in new and different
proteins, sometimes.
Science Test Review
Monarch
Viceroy
 Most predators have learned that the monarch butterfly makes a poisonous snack. The toxins from
the monarch's milkweed diet have given the butterfly this defense. In either the caterpillar or
butterfly stage the monarch needs no camouflage because it takes in toxins from the milkweed and
is poisonous to predators.
 State a hypothesis or explanation for why the Viceroy Butterfly looks like or evolved to look like the
Monarch?
 Convergent evolution – through variation in the Viceroy population they have slowly evolved to
look like Monarchs because animals don’t eat Monarchs due to the toxins.
