Question

The information from RNA to DNA are transferred by the process, which is called
A. Replication
B. Transcription
C. Translation
D. Reverse transcription

Answer 1

Hint: The central dogma of can be described as the two-step process – transcription and translation. In these processes, the information that presents in the genes flows into proteins from DNA to RNA and to protein. Transcription is the synthesis of an RNA from the segment of DNA by the help of RNA polymerase enzyme. The reverse process is known as reverse transcription.

Complete answer: 1. Replication: It is a biological process in which two copies of daughter DNA are formed from a single copy of parent DNA. It occurs in all living organisms and it is the most important event that takes for biological inheritance.
2. Transcription: It is a biological process in which one copy of RNA is produced from a DNA molecule. In this event, information transforms from DNA to RNA molecules. It is the first step of DNA base expression of the gene.
3. Translation: it is a biological process in which the synthesis of protein takes place inside the body. Here information carries from the RNA to protein.
In the question, it is asked about a process where information is transferred from RNA to DNA.
4. When information carries from DNA to RNA, it is called transcription, so, when RNA transfers the information to DNA it will be called Reverse transcription.
5. In biological terms, reverse transcription can be defined as a biological process in which an enzyme called reverse transcriptase is used to generate cDNA or complementary DNA from an RNA.

So, the correct answer is option D. Reverse transcription.

Note: The diagrammatic representation of reverse transcription is as follows:
