One can synthesize RNA from any gene in a test tube (in vitro). You want to synthesize mRNA from a prokaryotic gene in a test tube. You added the gene, which contains its promoter, coding region, and rho-dependent transcription termination site, in a test tube. Which of the following do you need to add to this test tube so that you can synthesize RNA from this gene and terminate transcription accurately? 1) RNA polymerase core enzyme, 2) RNA polymerase holoenzyme,3) RNA polymerase II, 4) ATP, CTP, GTP, and TTP mixture 5) ATP, GTP, CTP, and UTP mixture, 6) dATP, dGTP, dCTP, and dUTP mixture 7) Rho factor, 8) primer. 3,4,7 1,6,7 O2,5,7 2.4.6 2,5,7,8

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.
