Multiple Choice

Which DNA replication enzyme has a 5' → 3' exonuclease function to remove the primer?

Explanation:
During replication, the RNA primer that starts each short DNA segment must be removed and replaced with DNA. The enzyme that does this uses a 5' to 3' exonuclease activity to digest the RNA primer from its 5' end, while its own polymerase activity adds the correct DNA in its place. This combination of primer removal and DNA synthesis is characteristic of DNA polymerase I in bacteria. After the primer is removed and the gap filled, DNA ligase seals the remaining nick to make a continuous strand. Other enzymes listed either lack this 5' to 3' exonuclease function, or their primary roles are proofreading or sealing nicks rather than primer removal, so they don’t carry out this specific primer cleanup.

Common questions

Answers before you start.

What is DNA replication and why is it important?

DNA replication is the process by which a cell duplicates its DNA before cell division, ensuring each new cell receives the complete genetic information. This process is critical for growth, repair, and reproduction in all living organisms, maintaining genetic integrity across generations.

What topics are covered in a DNA replication exam?

A DNA replication exam typically covers key concepts such as the mechanisms of replication, enzyme functions (like DNA polymerase), replication models (semiconservative), and the significance of fidelity in replication. Understanding these topics is essential for students pursuing careers in genetics or molecular biology.

How can I prepare for a DNA replication exam effectively?

Preparing effectively for a DNA replication exam involves reviewing core concepts through textbooks, online resources, and participating in study groups. Practice questions are invaluable in testing your knowledge. Consider using resources like Examzify, which provides excellent tools for exam readiness.

What are the career options for someone specializing in DNA replication?

Specialists in DNA replication can pursue careers in research, genetics, biotechnology, and forensic science. In the biotechnology field, for instance, professionals can earn a salary around $80,000 annually, depending on experience and the specific job role within the industry.

Why is DNA storage gaining importance in the molecular biology field?

DNA storage is crucial due to its potential for long-term data preservation and its role in understanding genetic information. As data generation increases, DNA can provide a stable and compact medium for storing vast amounts of information, paving the way for innovations in data management and biology.
