All nuclei in multicellular animals' cells have the exact identical genes. However, the sets of genes transcribed in a cell varies dramatically from one cell to the next. Explain how gene transcription patterns are regulated in various cell types. • Describe one type of gene regulation that occurs after transcription is completed.
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.
