Select the description of an intron. (If possible, please explain why it is that answer) a.) sequence of adenine nucleotides added onto the end of pre‑mRNA b.) modified form of a guanine nucleotide added onto the end of pre‑mRNA c.) coding portion of a DNA sequence that is present in mature mRNA d.) noncoding portion of a DNA sequence that is removed from pre‑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.
