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.
The first stage of DNA-based gene expression is transcription, in which a portion (or the whole portion) of a gene's DNA is copied (transcribed) into RNA with the aid of a set of enzymes referred to as RNA Polymerases. A complementary strand of RNA is created by RNA polymerases using a template of single-stranded DNA. Each additional nucleotide is added to the 3' end of the strand as RNA polymerase constructs an RNA strand in the 5' to 3' orientation.
The coding strand (of the DNA) and the RNA sequence that was thusly transcribed are similar but not identical, according to the information above (RNA would code Uracil instead of Thymine).
