transfer RNA
messenger RNA
DNA sequence
DNA sequence
Which antibiotic inhibits interaction between t-RNA and m-RNA during bacterial protein synthesis?
Erythromycin
Neomycin
Streptomycin
Streptomycin
D.
Streptomycin
Tetracyclin interfere with the attachment of t-RNA carrying the amino acid to the m-RNA-ribosome complex preventing the addition of amino acids to the growing polypeptide chain. Streptomycin interfere with the initial steps of protein synthesis by changing the shape of 30S portion of 70S prokaryotic ribosome.
Erythromycin refers with 50S portion of the 70S prokaryotic ribosome.

Autosomal
Cytoplasmic
Y-linked
Y-linked
