An mRNA molecule, the first tRNA, and the small ribosomal subunit are the
components needed during the first stage of translation in prokaryotes. This stage is
called initiation _________________.

The _______________ loop of a tRNA is found at the bottom of the tRNA's cloverleaf
structure and it forms a base-pair interaction with the mRNA.

The three sites where RNA bind to the ribosome are......

Aminoacyl site , exit site, peptidyl site

nonsense mutations, base substitutions, etc.

Point
How is the process of translation initiation different between eukaryotes and
prokaryotes?
Give this one a try later!
- In eukaryotes, the initiating amino acid is methionine, not N-
formylmethionine
- Eukaryotic mRNAs do not have a ribosome binding sequence.
, typically, the ribosome uses which AUG codon it encounters in an mRNA as a signal
to start translation?

In translation, where do initiation, elongation, and termination steps take place?

All three take place on the ribosome
Rank the order of the binding sides on the ribosome in relation to the 5' to 3'
orientation of the mRNA (place site closest to the 5'end of the mRNA first)
