Reverse transcriptase is:
Correct answer: D. RNA-dependent DNA polymerase
- A. RNA-dependent RNA polymerase
- B. DNA-dependent RNA polymerase
- C. DNA-dependent DNA polymerase
- D. RNA-dependent DNA polymerase
Explanation
The term "reverse transcriptase" refers to an enzyme found in retroviruses (a type of RNA virus) that can synthesize a complementary DNA strand (cDNA) from an RNA template. This is a unique process because it involves the synthesis of DNA from an RNA template, which is the reverse of the typical flow of genetic information.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
