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.
What do you call the site of activators that bind to the DNA molecule ?
A. enhancer

Step by step
Solved in 3 steps
- A gene in liver cells is "off". In the presence of a toxin, a repressor is removed and the gene is transcribed at low levels. How would you describe this regulation? A. Positive induction B. Negative induction C. Positive repression D. Negative repressiond. give an example of an operon that is under negative control e. repressor f. give an example of a repressor molecule g. activator h. give an example of an activatorHow does tryptophan regulates its own production? a. When tryptophan levels are high, it binds to the trp repressor, which changes its shape and binds to the operator sequence in the trp operon. b. When tryptophan levels are high, it binds to the trp repressor, which changes its shape and binds to the promoter sequence in the trp operon. c. When tryptophan levels are high, it binds to the trp repressor, which changes its shape and falls off from the operator sequence in the trp operon. d. When tryptophan levels are high, it binds to the trp repressor, which changes its shape and falls off from the promoter sequence in the trp operon.
- Draw a schematic diagram showing the components involved in the regulation of the tryptophan operon.A cell has evolved in an environment that lacks a particular food source. However, when given this food in the laboratory, it is able to digest and use it for energy. Which of the following is likely true about the operon used to produce the enzymes needed for this metabolic process?

C The repressor is produced in the active state which causes it to bind to the promoter. O D The repressor is produced in the inactive state which causes it to bind to the promoter. 券Falsify and explain why each answer is right or wrong in detail.. How does the Trp operon work? A.
