Transcript Aim: What factors affect the expression of the gene?

 HAPPY FRIDAY
*HAVE OUT YOUR NOTECARDS*
Bellwork: Write down the following question and highlight
the key words in the question and answer.
In 1917 the biologist Thomas Hunt Morgan conducted studies in which he
kept some caterpillars in the dark and placed other under red, green, or blue
lights. Exposure to red light produced butterflies with brightly colored wings.
Exposure to green light resulted in dark-colored wings. Exposure to blue
light or no light resulted in pale-colored wings. What was the most likely
conclusion of Morgan’s research?
a) The pigment in butterfly wings absorbs light from the environment
b) The phenotypic expression of wing shape depends on color
pigmentation in butterflies.
c) The genes regulating wing color in butterflies are influenced by
environmental factors.
d) Caterpillars exposed to red and green light are healthier than
caterpillars exposed to no light or blue light.
What amino acids do the following
codons code for?
A) TTT
B) GAT
C) ACT
D) TAC
