Correct (Verified Solutions)- Portage
Learning
Anticodon region - Correct answer consists of a nucleotide triplet oriented in the 3' to
5' orientation that base-pairs to a precise mrna codon that is oriented in the 5' to 3'
direction
Ribosomes - Correct answer protein machinery; functions to bring mrna together with
the trna carrying an amino acid; its composed of 2 subunits (1 small and 1 large)
What does the small subunit have a binding site for? - Correct answer mrna
What are the 3 binding sites for the trna in the large unit? - Correct answer peptidyl-
trna binding site (P-site)
Aminoacyl-trna binding site (A-site)
Exit site (E-site)
,Peptidyle-trna binding site (P-site) - Correct answer functions to hold the trna
carrying the growing polypeptide chain firmly in place
Aminoacyl-trna binding site (A-site) - Correct answer serves to hold the trna carrying
the amino acid that is to be added next to the growing chain
Exit site (E-site) - Correct answer permits the passage of the trna molecules out of
the ribosome so that they can grab the appropriate amino acid for the next round of
addition to the growing chain
Exit tunnel - Correct answer allows passage of the polypeptide chain which is
continually growing in length as amino acids are added when its complete it is
released through the exit tunnel
Initiation - Correct answer assembly go the translation initiation complex
Initiator trna - Correct answer adds the MET and small ribosomal subunits bind here
, Translation initiation complex - Correct answer formed by the multi-unit complex
Amino end (N-terminus) - Correct answer the initial methionine located at the 5' N
terminus
Carboxyl end (C-terminus) - Correct answer the final amino acid is said to be located
at the 3' C-terminus
Elongation factors - Correct answer proteins that facilitate lengthening of the
polypeptide chain
What are the 3 steps termination of translation is broken down into? - Correct answer
1. Binding of a releasing factor
2. Liberation of the completed polypeptide chain
3. Disassembly of the translation initiation complex
