Which of the following are true regarding Sulfamethoxazole? Mark all correct answers. Sulfamethoxazole inhibits DNA gyrase, an enzyme involved in DNA replication and transcription. Sulfamethoxazole is part of the Sulfa group. Sulfamethoxazole inhibits folic acid synthesis, which is needed for nucleic acid synthesis. Sulfamethoxazole is a broad spectrum antibiotic. Sulfamethoxazole acts as an allosteric inhibitor. Which of the following are true regarding Polymixin B? Mark all correct answers. Polymixin B disrupts the outer membrane of bacterial cells. Polymixin B is a broad spectrum antibiotic. Polymixin B is effective against gram negative cells only. Polymyxin B inhibits bacterial ribosomes by altering the shape of the 30 S small subunit. Polymyxin B is found in neosporin triple antibiotic ointment.

Below is a figure comparing CTP on the left and CMP on the right. Based on these structures, and your understanding, which statement(s) below is/are CORRECT? [Choose all that apply.] Both CTP and CMP may be incorporated into a growing DNA strand by DNA polymerase. Assuming a C was matched incorrectly to an A, the proofreading function of DNA polymerase would release a CMP as a product. Assuming a C was matched incorrectly to an A, the proofreading function of DNA polymerase would release a CTP as a product. Only CMP may be incorporated into a growing DNA strand by DNA polymerase. Only CTP may be incorporated into a growing DNA strand by DNA polymerase.
