Which statement accurately describes the expression of genes in the nervous system? O Different neurons express different combinations of genes A small subset of the total human genome is expressed in the CNS. Every gene in the human genome is expressed in the CNS. Splice variants add diversity to brain function via beneficial mutations. O The genes that are expressed in the CNS are expressed equally in all neurons.
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.
