Actinomycin D inhibits DNA-dependent RNA synthesis. Thisantibiotic is added to a bacterial culture where a specific proteinis being monitored. Compared to a control culture, whereno antibiotic is added, translation of the protein declines over a period of 20 minutes, until no further protein is made.Explain these results.
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.
