Actinomycin A is a drug that prevents successful translation by inhibiting elongation. The most likely direct effect of this drug is to prevent the:

a. Binding of the large ribosomal subunit to the small subunit

b. breaking of the bond between tRNA and its amino acid

c. disassociation of the ribosomal subunits

d. start codon from binding

e. formation of peptide bonds between two tRNAs

Expert Solution

Ans) A

Binding of large ribosomal unit to smaller ribosomal unit. In cell biology,actinomycin A is shown to have the ability to inhibit transcription.Actinomycin A does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase.

Decide which sequence of events is most CORRECT for the initiation and elongation steps of translation in prokaryotic cells? (1) small ribosomal subunit binds to mRNA (2) initiator tRNA binds start codon on mRNA (3) active 70S ribosome is formed (4) translocation of ribosome (5) binding of second aminoacyl tRNA A. 2, 3, 1, 5, 4 B. 1, 2, 3, 5, 4 C. 2, 1, 3, 4, 5 D. 1, 2, 3, 4, 5 E. 1, 3, 2, 4, 5

What are the potential benefits of delegation, and when is it most likely to be successful? What are some guidelines on what to delegate? Why do some managers find it so difficult to delegate or share power? Write an essay on Steve Jobs style of functioning? Did he delegate his job effectively?

Cells that accumulate misfolded proteins initiate a stress response that includes reducing protein translation by inhibiting the initiation stage of translation. First explain the three stages of initiation of protein translation in eukaryotic cells. Next explain the mechanism by which translation is inhibited as part of the stress response. The three stages are 43S preinitiation complex, 48S initiation complex, and 80S initiation complex but I don't know how to explain them and what happens during each stage.
