Question 1 of 5
Select the following disorders characterized by inflammation of bronchi.
Correct Answer: B
Rationale: Step-by-step rationale: 1. Bronchitis is characterized by inflammation of the bronchi, leading to coughing and mucus production. 2. Asthma involves inflammation and narrowing of the airways but is not specific to bronchi. 3. Emphysema is a lung disease involving damage to the air sacs, not specifically inflammation of bronchi. 4. Tuberculosis is a bacterial infection affecting the lungs, not primarily characterized by bronchial inflammation. Summary: Bronchitis is the correct answer as it specifically involves inflammation of the bronchi, while asthma, emphysema, and tuberculosis do not primarily exhibit this characteristic.
Question 2 of 5
Which enzyme excises incorrect nucleotides on the newly synthesized DNA?
Correct Answer: E
Rationale: I'm sorry, but it seems like there was a mistake in the question as there is no option E provided. However, the correct enzyme that excises incorrect nucleotides on the newly synthesized DNA is DNA polymerase III. DNA polymerase III has a 3' to 5' exonuclease activity that allows it to proofread and remove incorrect nucleotides during DNA replication. DNA gyrase is involved in DNA supercoiling, RNA primase synthesizes RNA primers, and DNA ligase seals nicks in the DNA backbone. DNA polymerase II is involved in DNA repair.
Question 3 of 5
Which of the following enzymes removes 5' phosphate groups thereby preventing or decreasing the self-sealing of restricted plasmid vector molecules?
Correct Answer: A
Rationale: The correct answer is A: Calf intestinal phosphatase. This enzyme removes 5' phosphate groups from DNA molecules, preventing self-ligation of restricted plasmid vectors. This step is crucial in generating linearized vectors for downstream applications. Pyrophosphatase (B) hydrolyzes pyrophosphate bonds, not 5' phosphate groups. Phosphohydrolase (C) is a general term for enzymes that hydrolyze phosphoester bonds, not specific to 5' phosphate removal. Phosphate exonuclease (D) degrades nucleic acids by removing nucleotides from the 3' end, not the 5' phosphate group.
