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.
Compare and contrast the structure and function on ribosomes and proteasomes.
Ribosome
* Ribosomes are one of the cell organelles present in the cell
* In eukaryotes and prokaryotes one can see ribosomes present in them
*They are present in endoplasmic reticulum as well as in cytoplasm too.
* 70s( 50s and 30s) type of ribosomes present in prokaryotes whereas in eukaryotes 80s (60s and 40s) type of ribosomes are present.
* Proteasomes can be considered as specialized organelle for degradation of Targeted cellular proteins.
*These large multi subunits found in the cytosol attached to the endoplasmic reticulum (ER), and in the nucleus of eukaryotic cells
