Question

Which best compares DNA and RNA with regard to the process of protein production? DNA transforms from a nucleic acid into a protein, and RNA remains a nucleic acid. RNA transforms from a nucleic acid into a protein, and DNA remains a nucleic acid. DNA leaves the nucleus during the process and RNA remains in the nucleus. RNA leaves the nucleus during the process and DNA remains in the nucleus.

Answer 1

Out of the given statements "RNA leaves the nucleus during the process and DNA remains in the nucleus" compares the DNA and RNA to the best.

1. The basic principle is transfer of genetic information.
2. Central dogma is the process that explains the flow of genetic information from DNA to RNA and there by to proteins.
3. Functional units of DNA are genes which transcript to RNA
4. This process excludes the non functional regions of genes called introns.
5. Transfers the information from only the functional regions of genes called exons.
6. This makes a single stranded RNA with only the functional information from DNA.
7. Thus formed RNA moves out of nucleus and reaches ribosomes in cytoplasm.
8. Ribosomes provide the catalytic site for protein production that aids the amino acids to form as a chain with peptide bonds.
9. These strings of proteins are then directed to endoplasmic reticulum for folding into the required configuration to be as a subunit of the complete functinal protein.  
10. Thus formed proteins are stored and dispatched in vesicals for the required site of action by golgi bodies.
11. Thus DNA remains in the nucleus and RNA leaves the nucleus during protein production is supported.

Answer 2

Answer

C

Explanation:

DNA leaves the nucleus during the process and RNA remains in the nucleus.
