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.
Explain the process of how a protein is made and transported in/out of a cell starting with mRNA by trying to explain it in terms of a large scale process.
Protein synthesis is an complex procedure in eukaryotic cell involving various different organelles of the cell. Primarily an mRNA duplicating the information from the coding region of the DNA using RNA polymerase is synthesized through transcription. The mRNA synthesized floats into the cytoplasm and gets attached to the ribosome to initiate and elongate an amino acid chai. This synthesized amino acid chain will be folded and refolded in a particular way for a protein to be active and functional. Which is then transported out of the cell with the help of endoplasmic reticulum and Golgi bodies.
