Which of the following is NOT a reason cells regulate gene expression at a level other than the transcriptional level? Some proteins are only required in part of the cell and transcriptional control will only regulate the mRNA/protein throughout the cell. The core promoter for many genes is the same, so these genes will always be transcribed in the same cells. Differential gene expression in different cell types requires regulation of gene expression at levels other than transcription. Transcription and translation are realtively slow processes, so cells need to regulate gene expression post-transcriptionally if they require a fast change in expression of a gene. Not all cells are transcriptionally active (meaning they do not transcribe any genes), so these cells need to regulate gene expression post-transcriptionally.

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.
