Question

The flow of genetic material in microbial cells usually takes place from
A.RNA through DNA to proteins
B. proteins through RNA to DNA
C. DNA through RNA to proteins
D. none of these

Answer 1

Question:

The flow of genetic material in microbial cells usually takes place from

A.RNA through DNA to proteins

B. proteins through RNA to DNA

C. DNA through RNA to proteins

D. none of these

Concept:

Flow of genetic material in microbial cells- It is  usually a pathway of how genetic materials forms step by step.

Usually gene expression involves transcription of DNA into messenger RNA and translation of mRNA into protein.

Answer:

C. DNA through RNA to proteins. It is the right answer.

Explanation:

Transcription is the first stage. It is a process where  a gene's DNA sequence is copied (transcribed) to make an RNA molecule. Then translation occurrs. In this process by which a protein is synthesized from the information of messenger RNA (mRNA) which was contained in a molecule of mRNA.

This is how usually flow of genetic material takes place.

Thus, the right answer is option (C)DNA through RNA to proteins.
