A molecular biologist mutated a gene that encodes an enzyme (protein) that normally is secreted from the cell. The mutation resulted in the enzyme still being made, but it is now located in the cytoplasm. What do you think the molecular biologist changed in the cell coding this enzyme? a. The active site. b. The signal recognition particle (SRP). c. The signal sequence. d. The signal recognition particle receptor.
When grown in a greenhouse, the leaves of Aloe nobilis are green. When found in the desert in the wild, however, the leaves are often red. What BEST explains this observation? A. The environment affects the expression of A. nobilis genes. B. The sun changes the color of chlorophyll pigments. C. The plant uses red pigments for photosynthesis. D. The leaves become infected with a red parasite.

If a cell's DNA was mutated such that it lost the promoter of a gene, you would expect: a. That ribosomes wouldn’t bind to that gene b. No effect since the promoter doesn't have any coding information for the amino acids in the polypeptide c. Ribosomes would never stop translating that gene d. Transcription factors for that gene would no longer bind to activate expression of that gene e. tRNA would no longer bind to the codons of that gene

How are Bt crops created?a. by inducing plants to produce vitamin B and phytateb. by activating a cell surface receptor for Bt in bacteriac. by inserting a gene for glyphosate resistanced. by inserting a gene from Bacillus thuringiensis
Exposing Escherichia coli (e.coli) to ionizing radiation results in DNA damage. Say you perform an experiment and expose E. coli to increasing levels of ionizing radiation over time. After 180 minutes, all bacteria cells are found dead. 1. How do levels of LexA change over 180 minutes? Explain what is driving this change? 2. What changes in gene expression would occur over the course of the 180 minutes as a direct result of the changes in LexA levels? Detail how changing levels of LexA lead to such changes in gene expression.
