In some viruses the flow of information is in reverse direction, that is, from RNA to DNA. Can you suggest a simple name to the process?

Correct Answer

Reverse Transcription

Explanation

The question asks about the process where genetic information flows from RNA to DNA, which is the reverse of the normal transcription process (DNA to RNA). The textbook context defines transcription as 'the process of copying genetic information from one strand of the DNA into RNA.' When this flow is reversed in some viruses (like Retroviruses), where RNA serves as the genetic material and synthesizes DNA, the process is aptly called Reverse Transcription. This name logically follows from the concept that it is the reversal of the transcription process.

Solution Steps

  1. Step 1: Identify that normal transcription flows from DNA to RNA (as stated in context)

  2. Step 2: Recognize that the question describes the reverse flow (RNA to DNA)

  3. Step 3: Apply the term 'reverse' to 'transcription' to name this process
