Give one example of a prokaryotic system of gene expression that is more complicated (during transcription at the promoter) than its corresponding eukaryotic system of gene expression. A. prokaryotes require general transcription factors to initiate transcription B. prokaryotes typically have activator and repressor DNA sequences thousands of nucleotides away C. prokaryotes have three classes of RNA polymerases D. prokaryotes always have their DNA tightly packed into higher-level structures than nucleosomes E. prokaryotes usually have polycistronic mRNA
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.
