Biology Question on human health and disease

Transcription refers to:

A

(A) Transfer of genetic information of DNA in the form of the genetic codon of mRNA

B

(B) Transfer of genetic information of RNA in the form of the genetic codon of DNA

C

(C) Transfer of genetic information of RNA in the form of the genetic codon of mRNA

D

(D) Transfer of genetic information of DNA in the form of the genetic codon of rRNA

Answer

(A) Transfer of genetic information of DNA in the form of the genetic codon of mRNA

Explanation

Solution

Explanation:
Transcription is the process by which the information in a strand of DNA is copied into a new molecule called messenger RNA (mRNA). The segments of DNA are transcribed into RNA molecules that encode proteins are said to produce messenger RNA.DNA contains the genetic information of an individual organism which is transferred to the newly synthesized mRNA as it contains the cistron. Gene that codes for a particular protein or enzyme is also called a cistron. It forms the largest element in the gene that encodes for a polypeptide gene. mRNA can be monocistronic or polycistronic.Hence, the correct option is (A).
