MOLECULAR BIOLOGY Flashcards
1
Q
Action of steptomycin
A
- Acts only on bacteria
- prevents the transition from translation initiation to chain elongation and also causes miscoding
2
Q
Action of Erythromycin
A
- Acts only on bacteria
- Binds in the exit channel of the ribosome and thereby inhibits elongation of the peptide chain
3
Q
Action of puromycin
A
- Acts on bacteria and eukaryotes
- causes the premature release of nascent polypeptide chains by its addition to the growing chain end
4
Q
Action of cycloheximide
A
- acts only on eukaryotes
- blocks the translocation reaction on ribosomes
5
Q
Action of tetracycline
A
- Acts only on bacteria
- Blocks binding of aminoacyl-tRNA to A site on ribosome
