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 how eukaryotic mRNAs are modified to have a cap and a tail.
Biomolecules are the compounds that are necessary for different biological processes occurring in a cell. These compounds may include large molecules like lipids, nucleic acids, carbohydrates, and proteins or small molecules like primary and secondary metabolites. Biomolecules are generally synthesized in the body of an organism only but some organisms may also require biomolecules in their diet also.
RNA or ribonucleic acid is a polymer of ribonucleotides connected together via a phosphodiester bond. An RNA molecule either functions as information encoding molecule, catalytic molecule or regulatory molecule in a cell.
An mRNA molecule decodes the information for the synthesis of protein is stably encoded in the DNA and an mRNA molecule is synthesized during transcription that takes on the information in cytoplasm from the nucleus for protein synthesis.
