What is the function of a protein kinase? What amino acids are often phosphorylated by kinases?
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.

All cells receive and respond to signals from their surroundings. Each cell is programmed to respond to specific extracellular signal molecules. Extracellular signally usually involves the following mechanism:
- Synthesis and release of the signalling molecules by the signalling cell.
- Transport of the signal molecule to the target cells.
- Binding of the signal by a specific receptor leading to its activation.
- Initiation of signal transduction pathways.
