Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

An mRNA has some additional sequences that are not translated and are referred to as untranslated regions (UTR).

The ribosome acts as a catalyst (23S rRNA in bacteria is the enzyme- ribozyme) for the formation of a peptide bond.

The ribosome consists of structural RNAs and about 60 different proteins.

For initiation, the ribosome binds to the mRNA at the start codon (AUG) that is recognised only by the initiator tRNA.
