Which one of the following does not follow the central dogma of molecular biology?
Correct answer: D. HIV
- A. Pea
- B. Mucor
- C. Chlamydomonas
- D. HIV
Explanation
The oneway flow of information from DNA to mRNA and then to protein is known as the central dogma of molecular biology by F.H.C. Crick (1958). But later on, two American workers, H. Temin and D. Baltimore, reported that DNA is also formed from RNA in retroviruses such as HIV. This is called reverse transcription. This reverse transcription occurs under the influence of the reverse transcriptase enzyme. So, HIV does not follow the central dogma.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
