What is the name of the groups of 3 nitrogen bases found in mRNA?

• anticodon

• codon

• nitrogenous base

Codons code for specific

• proteins

• nucleic acids

• nitrogen bases

• amino acids

Which ones are the special codons?

• 3 for start and 1 for stop

• 1 for start and 3 for stop

Which molecule brings the amino acid?

• mRNA

• tRNA

• rRNA

Where is the anticodon found?

• in the mRNA

• in the rRNA

• in the tRNA

The anticodon in the tRNA is complementary with the 

• codon in mRNA

• codon in rRNA

The first step of translation is called initiation. When is initiation complete?

• when the large ribosomal subunit joins to the small one

• when the small ribosomal subunit joins the mRNA

When there is a tRNA in the P site and another one in the A site, a ________ bond forms between the two amino acids

• hydrogen

• covalent

• peptide

When will the step of elongation finish?

• when we reach a start codon on the mRNA

• when we reach a stop codon in the mRNA

What is the purpose of translation?

• produce polypeptides

• produce tRNA

• produce mRNA
