Question

Which of the following statement is true about the transfer of genetic information?

• A. Genetic information is transferred from nucleus to cytoplasm of the cell through RNA
• B. Genetic information is transferred from the nucleus to the cytoplasm of the cell through DNA
• C. Genetic information is transferred from the nucleus to the cytoplasm of the cell through ACTH
• D. Genetic information is transferred from the nucleus to the cytoplasm of the cell through Lysosomes

Answer 1

The correct option is A

Genetic information is transferred from nucleus to cytoplasm of the cell through RNA

The correct option is A

Explanation of the correct option:

1. The genetic information is carried from the nucleus to the cytoplasm within the cell via RNA (ribonucleic acid).
2. In the eukaryotes, once the pre-mRNA or precursor mRNA (messenger RNA) gets transcribed from DNA (deoxyribonucleic acid), it is processed to mature mRNA.
3. This removes the non-coding sections or introns of the pre-mRNA.
4. The mRNA is then exported to the cytoplasm from the nucleus, where it is bound to ribosomes and translated into its corresponding protein kind with the assistance of tRNA or transfer RNA.
5. The RNA is a polymeric molecule, it performs essential biological roles in decoding, coding, expression of genes, and regulation.

Explanation of the incorrect option:

Option B:

1. The genetic information is transferred from DNA to RNA by the process of transcription.
2. Thus, DNA gets converted to RNA at the time of transferring genetic information.

Option C:

1. ACTH or adrenocorticotropic hormone is a hormone secreted by the pituitary gland.
2. This hormone monitors the generation of cortisol hormone.
3. The hormone cortisol is released by the adrenal gland and regulates the blood pressure, blood sugar, and stress response.
4. The hormone ACTH has no role in transferring genetic information.

Option D:

1. The membrane-bound organelles, which comprise a group of enzymes, which possesses the tendency to dissociate all the kinds of biological polymers like nucleic acid, proteins, lipids, and carbohydrates are lysosomes.
2. Lysosomes serve as the digestive system of the cell functioning both to digest the obsolete constituents of the cell itself and to degrade the substances taken up from external of the cell.
3. Lysosomes have no role in transmitting genetic information from the nucleus to the cytoplasm.

Final answer: Genetic information is transmitted from the nucleus to the cytoplasm of the cell via RNA.
