    What is the central dogma?

    It describes the flow of genetic information from DNA to RNA to protein.

    Who discovered the central dogma?

    Francis Crick in 1958.

    Why did Crick call it the central dogma?

    He wanted to emphasize its central and powerful role in biology.

    What happens during transcription?

    DNA information is copied into RNA.

    What is the role of RNA in protein synthesis?

    It directs the amino acid sequence of proteins.

    How does translation differ from transcription?

    Translation converts RNA into proteins, while transcription converts DNA into RNA.

    What is reverse transcription?

    The process of converting RNA back into DNA.

    Why is reverse transcription an exception to the central dogma?

    It allows RNA to serve as a template for DNA synthesis.

    What are prions?

    Infectious proteins that can cause disease without nucleic acids.

    What is a mutation?

    A change in the DNA sequence that can affect gene function.

    What are the types of RNA?

    Messenger RNA, Transfer RNA, and Ribosomal RNA.

    What is the function of transfer RNA?

    It transports amino acids to the site of protein synthesis.

    What is the primary structure of proteins?

    The linear sequence of amino acids in a polypeptide chain.

    What distinguishes fibrous proteins from globular proteins?

    Fibrous proteins are elongated and structural, while globular proteins are compact and functional.

    What causes mutations?

    Factors like environmental damage, replication errors, or chemical exposure.
