Gene A Gene B Gene C Low levels of gene A transcription generates some transcripts of the gene. | No transcription of gene B leads to no synthesis of protein B. Continuous transcription of gene C generates many transcripts of the gene. Translation of each of the gene A transcripts generates some protein A. Translation of each of the gene C transcripts generates many molecules of protein C. FIGURE 7.4 The Level of Gene Expression Can Be Controlled ?

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.
