RNA and Transcription

What is the primary difference between traditional vaccines and mRNA vaccines?

• Traditional vaccines modify the DNA of the recipient.

• mRNA vaccines are less effective than traditional vaccines.

• Traditional vaccines use parts of the virus, while mRNA vaccines use genetic instructions.

• mRNA vaccines use live viruses, while traditional do not.

What is the role of RNA polymerase in the transcription process?

• It modifies mRNA after transcription.

• It assists in the splicing of mRNA.

• It binds to DNA and helps form mRNA.

• It translates mRNA into proteins.

What is the purpose of the 'cap' and 'poly A tail' added to mRNA?

• They splice the mRNA to remove unnecessary segments.

• They help the mRNA leave the nucleus.

• They prevent the mRNA from being translated into protein.

• They protect mRNA from degradation and assist in its export from the nucleus.

What does the central dogma of molecular biology state?

• Proteins can be used to synthesize DNA and RNA.

• Information flows from proteins to RNA to DNA.

• Information flows from DNA to RNA to proteins.

• RNA can replicate independently of DNA.

What is alternative splicing?

• A process that degrades mRNA molecules.

• A process that allows a single gene to code for multiple proteins.

• A technique to prevent mRNA from leaving the nucleus.

• A method to translate proteins directly from DNA.
