What are the two major molecules that make up ribosomal subunits? Recalling information from chapter 2, identify the buildingblocks for each of these molecule types.
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.

Ribosomes are macromolecules found in abundant quantities in the cells of living cells. An actively dividing eukaryotic cell contains around 10 million ribosomes. Ribosomes are the sites of protein synthesis. In prokaryotic cells, the ribosomes are found floating freely in the cytoplasm, while in eukaryotes they are attached to the endoplasmic reticulum.
The DNA is transcribed to form the mRNA, which is a sequence of nucleotides having information on the amino acid sequence that would make the intended protein. Ribosomes bind to the mRNA, and corresponding tRNA molecules for each codon enter the ribosomes, bind to mRNA, and start synthesizing amino acid chains. The synthesized protein then assumes the final 3D conformation to become functional.
