When would a ribosome bind to a promoter sequence?
A) It wouldn't. A promoter is a DNA sequence, and ribosomes don't bind to DNA.
B) When the ribosome needs to transcribe the gene that that promoter controls.
C) When the ribosome is translating the DNA sequence of a gene.
D) When there is a start codon (AUG) in the promoter sequence.

A particular strain of λ (lambda) can lysogenize its E. coli host at 30°C, but not at 42°C. Could a temperature-sensitive mutation in the int (integrase) gene explain this phenotype?
A. There is insufficient information to answer the question.
B. No
C. Yes
In gene silencing, the “dicer” enzymea. assembles siRNAs into a RISC complex.b. unwinds the RISC complex.c. binds siRNA to mRNA sequences complementary to it.d. slices up double-stranded RNA molecules
