Regarding eukaryotic genes, it is correct to state that: a) Distal enhancer-like elements decrease the intensity of gene transcription activation b) Mutations in intronic regions of a gene can alter the levels of its corresponding protein c) They are regulated only by promoter regions, being activated or repressed by the presence of transcription factors d) The junctions of exons and introns are recognized by splicing factors, which guarantee the production of the same mRNA regardless of cell type. e) Activator and repressor proteins bind to the coding region of genes, regulating the
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.
