• codon

• anticodon

• triplet

Codons are complementary to __________ on tRNAs.

• codes

• AUG

Name the molecules that bring specific amino acids from the cytoplasm to the ribosome.

• mRNA

• tRNA

• aminoacyl tRNA

• ATP

NGSS.HS-LS1-1

Name the enzyme that catalyses the binding of an amino acid to a correct tRNA by using the ATP.

• peptidyl transferase

• mRNA synthetase

• aminoacyl-tRNA synthetase

• ribozyme

During initiation of translation process, the mRNA attaches to the _____________ at its ________ .

• large ribosomal subunit, 3' end.

• small ribosomal subunit 5' end.

• large ribosomal subunit, 5' end.

• small ribosomal subunit, 3' end.

An initiator tRNA, with the anticodon_____ , carries the amino acid ______________.

• UAC, serine

• UAC, methionine

• AUG, alanine

• AUG, methionine

During initiation of translation process, the initiator tRNA sites in the _______ of ribosome and the vacant _______ is ready for the next aminoacyl-tRNA.

• A site , P site

• A site, E site

• P site, E site

• P site, A site

Elongation stage of translation process involves a 3-step cycle:

• codon recognition

• peptide bond formation

• peptide bond is hydrolysed

• translocation
