Which is the most inappropriate description of a ribosome?
Select one:
a. It consists of proteins and rRNAs.
b. It has pockets for at three tRNA bindings.
c. For initiation, the 30S subunit binds to mRNA before the 50S subunit binds.
d. For its translational function, ribosome needs other protein factors.
e. Ribosomes carry out translation at consumption of the energy from ATP.
Homework Answers
1. Answer: Option E
is correct
Explanation:
The ribosome is composed of rRNA and ribosomal proteins
It contains E, P, and A sites for tRNA binding.
The small subunit first binds to the mRNA
Ribosome requires the help of initiation, elongation, and release
factors.
Ribosomes mediate peptide bond formation with the help of peptidyl
transferase activity.
Translation by ribosomes is driven by GTP hydrolysis.

Which is incorrect about the initiation of translation? Select one: a. 30S subunit binds to mRNA first by recognizing the Shine-Dalgarno sequence on mRNA. b. In bacteria, most of the starting Met codon is specifically for N-formyl methionine (fMet). c. After fMet-loaded tRNA is bound, the 50S subunit binds to make the complete translational complex. d. A complete ribosome complex migrates on an mRNA until it finds the Shine-Dalgarno sequence. e. All of these
