Low TPP (Transcription is completed.) HIgh TPP (Transcription is attenuated.) Transcription continues to the TPP Terminator stem-loop end of the thi operon. Switch UUUUU 3' Transcription ends at the U-rich sequence. 50 Antiterminator stem-loop
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.
Which RNA conformation favors transcription—the form with the antiterminator stem-loop or the form with the terminator stem-loop?
