Which component is the last to join the initiation complex during the initiation of translation?
Vika [28.1K]

Answer:

The correct answer is the third option- the large ribosomal unit.

Explanation:

The translation is the second process of the protein synthesis in which transcribed mRNA molecule and transfer RNA or tRNA and ribosomes assemble together and complete synthesis of peptide chain or protein.

The assembly of initiator tRNA to ribosome subunits at the start codon of the mRNA is the initiation complex of the translation. The initiator tRNA is basically a met-tRNA molecule.

The initiator tRNA is bound to small subunit (30S) at 5' cap and scan for the start codon of mRNA.

Start codon bind to initiator RNA and in the end larger ribosomal unit assemble to this complex to complete the initiation complex of translation.

Thus, the correct answer is option - the large ribosomal subunit

netineya [11]

Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.

Explanation:

The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.
