Ans. Translation.
Protein synthesis involves transfer of information from parent DNA to RNA by by the process of transcription and from RNA to protein by the process translation.
Translation occurs in ribsomes, during which information present in mRNA as triplet codons is used to synthesize polypeptide chains or proteins. Each genetic code codes for a specific amino acid and adds it to the growing polypeptide chain.
The correct answer for the question presented above is organ transplantation between species. Having knowledge of evolutionary relationships help in successfully transplanting organs to different species based on the fact that some species share similar DNA characteristics. This allowed us to discover that transplant between species is possible.
