Verified step by step guidance

Understand the process of reverse transcription: it is a unique mechanism used by retroviruses to convert their genetic material from one form to another.

Recall that retroviruses have RNA as their genetic material, unlike most organisms that have DNA as their genetic material.

Recognize that reverse transcription involves using RNA as a template to synthesize complementary DNA (cDNA), which is the reverse of the usual transcription process where DNA is used to make RNA.

Differentiate reverse transcription from other processes: DNA transcription (DNA to mRNA), DNA replication (DNA to DNA), and protein synthesis (mRNA to protein).

Conclude that reverse transcription specifically refers to the synthesis of DNA from an RNA template, which is essential for retroviruses to integrate their genome into the host DNA.
