What does a bacterial RNA polymerase produce when it transcribes a protein-coding gene?

a. rRNA

b. tRNA

c. mRNA

d. pre-mRNA

Expert Solution & Answer

Summary Introduction

Introduction:

The RNA (ribonucleic acid) polymerase is a multi-subunit enzyme. It catalyzes the transcription of DNA (deoxyribonucleic acid) into different types of RNA, such as m-RNA (messenger RNA), t-RNA (transfer RNA) and r-RNA (ribosomal RNA).

Answer to Problem 4TYK

Correct answer:

The bacterial RNA polymerase produces mRNA (messenger RNA) when it transcribes a protein-coding gene.

Explanation of Solution

Explanation/Justification for the correct answer:

Option (c) is given that mRNA is produced by the bacterial RNA polymerase when it transcribes a protein-coding gene. The amino acids (building blocks of protein) are encoded by mRNA. Therefore, the mRNA is formed when the bacterial RNA polymerase transcribes the protein-coding genes. Hence, option (c) is correct.

Explanation for incorrect answers:

Option (a) is given that rRNA (ribosomal RNA) is produced by the bacterial RNA polymerase when it transcribes a protein-coding gene. The rRNA is found in ribosomes. The rRNA plays a catalytic role in the process of translation, but the major role is played by m-RNA. So, it is an incorrect option.

Option (b) is given that tRNA (transfer RNA) is produced by the bacterial RNA polymerase when it transcribes a protein-coding gene. The tRNA helps to decode the mRNA sequence into a functional protein. So, it is an incorrect option.

Option (d) is given that snRNA (small nuclear RNA) is produced by the bacterial RNA polymerase when it transcribes a protein-coding gene. The snRNA helps in the splicing process to produce the mature mRNA. So, it is an incorrect option.

Hence, options (a), (b), and (d) are incorrect.

Conclusion

Thus, it can be concluded that a bacterial RNA polymerase produces mRNA when it transcribes a protein-coding gene.
