Many antibiotics, which are molecules that are toxic to bacteria, function as enzyme inhibitors. Imagine that both Antibiotic A and Antibiotic B inhibit the ribosome. Antibiotic B kills the bacteria. In contrast, Antibiotic A only temporarily stops growth, with the bacteria remaining alive and able to resume growth when the antibiotic is removed. Which of the following statements provides a reasonable explanation for the difference between Antibiotic A and Antibiotic B? Antibiotic A is a competitive enzyme inhibitor whereas Antibiotic B is a non- competitive enzyme inhibitor. Antibiotic A is a reversible enzyme inhibitor whereas Antibiotic B is a non- reversible enzyme inhibitor. Antibiotic A is a non-reversible enzyme inhibitor whereas Antibiotic B is a reversible enzyme inhibitor. Antibiotic A is a non-competitive enzyme inhibitor whereas Antibiotic B is a competitive enzyme inhibitor.

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
