T3L6 Flashcards
1
Q
Ribosome
A
Interprets code and are mainly made of RNA (+ accessory proteins)
-> associated with endoplasmic reticulum (free in cytosol)
2
Q
Large and Small Ribosome
A
Large - 49 proteins, 3 RNA
Small - 33 proteins, 1 RNA
3
Q
3 sites of ribosome
A
EPA
4
Q
Tetracycline
A
Block binding of aminoacyl-tRNA to A-site of ribosome
5
Q
Streptomycin
A
Prevent transition from initiation complex to chain elongating ribosome -> causes miscoding
6
Q
Chloramphenicol
A
Block peptidyl transferase reaction on ribosome
7
Q
Cycloheximide
A
Block translocation reaction on ribosome
8
Q
Rifamycin
A
Block initiation of RNA chain by binding to RNA polymerase
9
Q
microRNA
A
21-22nt non-coding RNA
Bind target sequences
