Question

Transfer of information from molecule of DNA to mRNA is called as
A. Transcription
B. Translation
C. Replication
D. None of the above

Answer 1

Hint: The core dogma of can be summarised as a two-step transcription and translation process. The information stored in the genes is transferred from DNA to RNA and then to proteins in these processes. Transcription is the process of creating RNA from a DNA sequence using the RNA polymerase enzyme. The opposite of transcription is reverse transcription.

Complete answer:
Option A: It is a biological process in which a DNA molecule produces one copy of RNA. Information is transferred from DNA to RNA molecules in this action. It is the first step in the gene's DNA base expression.
So, option A is correct.
Option B: It is a biological process in which the body's protein synthesis takes place. Here, information is transferred from RNA to protein.
So, option B is not correct.
Option C: It's a biological process in which a single copy of parent DNA produces two copies of daughter DNA. It is the most crucial event in biological inheritance that occurs in all living creatures.
So, option C is not correct.
Option D: Transcription is the process of transferring information from a DNA molecule to mRNA. Translation is the process of converting mRNA into the amino acid sequence of a protein. Replication is the process of making two identical copies of DNA from a single double-stranded DNA molecule.
So, option D is not correct.

So, option A is the correct answer.

Note:
The big molecule deoxyribonucleic acid (DNA) contains genetic information. This data is converted into RNA, which is then translated into proteins. Gene expression is the term for this process.
A gene is a short piece of DNA that includes the instructions for making proteins. The double helix structure of DNA makes it a huge, complicated molecule. A set of events occur when information from DNA or a gene is encoded. Gene expression is the term for this process.
Transcription and translation are two steps in the process of gene expression. Transcription is the transfer of information for protein synthesis from DNA to mRNA, whereas translation is the synthesis of protein from mRNA.
