Central Dogma MCQ with Answers Pdf

What is central dogma?

  • The central dogma refers to the process of transcription and translation in which genetic information is passed from DNA to RNA, and then from RNA to protein, and the process of replication in which genetic information is passed from DNA to DNA.
  • The central dogma refers to the transmission process of genetic information in the process of replication, transcription, translation, etc.
  • The term central dogma was proposed by Francis Crick. 
  • The central dogma includes three processes: DNA biosynthesis, RNA biosynthesis, and protein biosynthesis.
  • The central dogma embodies the two basic functions of DNA:
  • The transmission of genetic information is mainly completed through DNA replication, which occurs in the reproductive process or cell proliferation process of parents producing offspring.
  • The expression of genetic information is accomplished through transcription and translation, which occur during individual development.
