Initiation, the first step of translation begins when the start codon AUG enters which site of the ribosome?
A (aminoacyl) site
P (peptidyl) site
E (exit) site
R (repair) site
Elongation, the second step of translation begins when the start codon AUG enters which site of the ribosome?
A (aminoacyl) site
P (peptidyl) site
E (exit) site
R (repair) site
The peptide (protein) bond occurs when two amino acids are between which two sites of the ribosome? Select both.
A (aminoacyl) site
P (peptidyl) site
E (exit) site

As elongation continues, which site allows the tRNA and newly formed polypeptide to leave the ribosome?
A (aminoacyl) site
P (peptidyl) site
E (exit) site
R (repair) site
Protein translation ends when a stop codon reaches which site?
A (aminoacyl) site
P (peptidyl) site
E (exit) site
R (repair) site
The three stop codons are the ONLY codons which do not code for an amino acid.
TRUE
FALSE
After translation, which of the following can be reused to make more proteins?
Ribosome
tRNA
mRNA
All options
After translation, the protein moves to which organelle for folding and modification?
Rough ER
Smooth ER
Golgi
Vessicle
If the mRNA codon is AUG, what amino acid be added to the growing polypeptide?
Met
Glu
Ala
Phe
What model of a biological process is shown?
Mitosis
Transcription
DNA Replication
Translation
Which organelle is the location where protein is made?
Ribosome
Nucleus

Nucleotide
Explain how the ribosome ensures the correct sequence of amino acids in a protein.
By matching the anticodon of tRNA with the codon on mRNA
By synthesizing mRNA from a DNA template
By forming peptide bonds between amino acids
By transporting amino acids to the nucleus
Explain how mRNA is translated into a protein.
mRNA is transcribed from DNA and then directly forms a protein
mRNA is read by the ribosome, and tRNA brings the corresponding amino acids to form a polypeptide chain
mRNA is replicated to form a double-stranded molecule
mRNA is degraded by nucleases
