A scientist is interested in producing flowers with a darker red color. To do this, the scientist alters the promoter of the gene to make it more active. This results in increased transcription and increased red pigments. The scientist then alters the promoter to make it even more active. This results in white flowers with no red pigment. Genetic research showed an increase in the siRNA in the cell. What did the siRNA do to the mRNA? A. The siRNA caused the mRNA to be broken down. B. The siRNA caused alternative splicing of the mRNA. C. The siRNA caused increased methylation of the mRNA. D. The siRNA caused the ribosome to no longer recognize this mRNA.
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.
