Questions and Answers

What does the central dogma of molecular biology involve?

  • The process of transcription and translation (correct)
  • Mutation and genetic drift
  • DNA replication and gene expression
  • Cell division and protein synthesis
  • Why is transcription considered a necessary process in biology?

  • It directly produces energy for the cell.
  • It is required for cell division.
  • It helps in the elimination of mutated genes.
