Which one of the following does not follow the central dogma of molecular biology?

  • A
    Pea
  • B
    Mucor
  • C
    Chlamydomonas
  • Correct answer
    D
    HIV

Solution

The central dogma of proteins synthesis is expressed as $$ \text { DNA } \stackrel{\text { Replication }}{\longrightarrow} \text { DNA } \stackrel{\text { Transcription }}{\longrightarrow} \text { RNA } $$ $\stackrel{\text { Translation }}{\longrightarrow}$ Protein Temin described the presence of an enzyme, reverse transcriptase or RNA dependent DNA polymerase, which controls the synthesis of DNA from a single strand of RNA. D Baltimore also described the presence of this enzyme in RNA tumour viruses. The presence of this enzyme changed the central dogma of protein synthesis into central dogma reverse Figure

Hence, the correct answer is option: 'D'.
