Questions and Answers

What is the role of messenger RNA (mRNA) in protein synthesis?

  • Transcribes the genetic information from ribosomes
  • Initiates the process of gene transcription
  • Carries the genetic instructions from DNA to ribosomes (correct)
  • Directly assembles amino acids to form proteins

What is the reason behind the disorderly organization of genes in genomes?

  • Environmental influences on gene organization
  • Chaotic evolutionary histories of organisms (correct)
  • Genetic changes driven by natural selection
  • Inefficient transcription and translation processes

What are the components involved in the translation process to build a corresponding protein?

  • Genetic drift and natural selection
  • DNA and messenger RNA (mRNA)
  • Introns and exons
