Which of the following is NOT a method by which bacteria can be resistant to antibiotics? Select one: a. Utilise an alternate pathway of gene expression that is not targeted by the antibiotic. b. Alter the binding site of the antibiotic, to either prevent it binding, or remove it from the site. c. Production of enzymes that bind to and break down the specific antibiotic. d. Production of a cell membrane pump that translocates antibiotics outside the cell. A potential side effect of antibiotic use is a secondary bacterial or fungal infection, usually associated with regions like the skin, upper-respiratory tract or genitalia. What is the most likely reason for the formation of these secondary infections? Select one: a. Antibiotics do not work on viruses, so they are able to establish infections in these locations. b. Organisms that are antibiotic resistant are usually more virulent, meaning they can survive and cause infection. c. The antibiotic kills off normal flora, providing an opportunistic pathogen the chance to thrive there. d. The antibiotic compounds will damage the host’s cells at these sites, providing a site of entry for a pathogen.
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.
