According to the central dogma of molecular biology, genetic information flows:

Answer: DNA to RNA to Protein.

  • A Protein to RNA to DNA
  • B RNA to DNA to Protein
  • C DNA to RNA to Protein
  • D DNA to Protein to RNA

Correct answer: C. DNA to RNA to Protein

Explanation: The central dogma proposed by Francis Crick states that genetic information flows from DNA to RNA to protein.

The Replication Forkhelicase (unwinds fork)leading strand (continuous, 5'→3')lagging strand: Okazaki fragments (discontinuous)

Helicase unwinds the double helix at the replication fork; one new strand (leading) is synthesised continuously toward the fork, while the other (lagging) must be made in short, separate Okazaki fragments because DNA polymerase only adds nucleotides 5'→3'.

Concept context

DNA structure, replication, transcription, translation, the genetic code, and gene regulation (lac operon). The single most important chapter for NEET molecular biology.
