You complete a comparative transcriptomics experiment, where RNA from a plant sample grown in sandy soil is compared to RNA from a plant sample grown in silty soil to learn about differences in regulation of gene expression in these two environments. In preparation for an RNA microarray experiment, the sample grown in sandy soil is labeled with green fluorescence and the sample grown in silty soil is labeled with red fluorescence. What color result(s) would you expect for: A gene that is expressed only in the plant grown in a sandy soil environment? An expressed gene that is expressed, but at equal levels in both samples? a gene that is involved in the trait studied, adaptation to the local soil type? [Choose ] [Choose ] [Choose ]
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.
