Prokaryotic Translation

The process of polymerization of amino acids to form a polypeptide chain is called___________

• Translation
• Transcription

• Transformation

• Replication

The codon in the mRNA is read by ______ in the tRNA molecule

• Nucleotides

• Nitrogenous bases

• Purines and pyramidines

• Anticodon

Answer explanation

Because they are complementary to the sequence in the mRNA.

In prokaryotes ribosome exist as___________

• 70s

• 80s

• 30s

• 50s

Which is the adaptor molecule in translation process?

• RNA

• rRNA

• tRNA

• mRNA

Answer explanation

Because they carry amino acids from the amino acid pool to the site of protein synthesis.

The process of adding amino acids to the tRNA molecule is called

• Amino acylation of tRNA molecule.

• Discharging of the tRNA molecule.

• Transfer of amino acid to the tRNA

• Coding of amino acid to the tRNA

What does S in the name of the subunits of the ribosomes denotes?

• Svedberg unit

• Salmanazar unit

• Sazhen unit

• Sack unit

What is a translation unit in the mRNA?

• A nucleotide sequence

• A coded language of the proteins

• A sequence which starts with a start codon and ends with a stop codon coding for a polypeptide sequence

• A complementary sequence of the template DNA

In translation, this is not an essential component

• Amino acid

• Ligase

• mRNA

• Anticodon

Translation occurs in the

• Nucleus

• Cytoplasm

• Lysozyme

• Mitochondria

This identifies a particular amino acid and its cognate tRNA molecule

• Topoisomerase

• tRNA synthetase

• rRNA

• tRNA
