RNA polymerase In the absence of the Inducer, this roprossor proteln blocks transcription. The presence of the Inducer causes a conformational chango that Inhbits the ability of the ropressor protaln to bind to the DNA. Transcription proceeds. Promoter DNA MRNA - Repressor proten No transcription Transcription occurs or -Inducer -Repressor protaln (e) Repressor protaln, Inducer molocula, Inducible gene This activator protein carnot bind to the DNA unless an Inducer is present. When the Inducer is bound to the activator protein, this enables the activator protain to bind to the DNA and activate transcription. Inducer RNA polymerase No transcription or Activator proten Transcription occurs Activator protein (b) Activator protain, Inducer molecule, Inducible gene In the absence of a corapressor, this repressor protein wil not bind to the DNA. Therofore, transcription can occur. When the coropressor Is bound to the repressor protein, a conformational change occurs that allows the repressor to bind to the DNA and inhbit transcription. RNA polymerase Transcription occurs or No transcription Corepressor -Repressor protein Ropressor protein (c) Repressor protein, corepressor molecule, repressible gene This activator protein will bind to the DNA without the ald of an offoctor molecule. The prosence of an Inhibitor causes a conformational chango that Inhibits the ability of the activator protein to bind to the DNA This Inhibits transcription. RNA polymerase No transcription -Inhibitor Transcription occurs Activator or protein Activator proteh (d) Activator protein, Inhibitor molecule, repressible gene
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 of these are genetic regulatory proteins and which are small effector molecules?
