Say you have an operon called the CAKE operon, it contains genes for the enzymes require to convert C into E via following steps C-->A-->K-->E. 1) if this operon is *inducible*, the maximum level of the enzymes for A-->K is most likely made when there is: a) high level of C b) high level of E c) low level of C d) low level of E e) unpredictable - depends on whcih is the inducer molecule 2) if the operon is *repressible*, the maximum level of the enzymes for A-->K is most likely made when there is: a) high level of C b) high level of E c) low level of C d) low level of E e) unpredictable - depends on whcih is the co-repressor molecule
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.
Say you have an operon called the CAKE operon, it contains genes for the enzymes require to convert C into E via following steps C-->A-->K-->E.
1) if this operon is *inducible*, the maximum level of the enzymes for A-->K is most likely made when there is:
a) high level of C
b) high level of E
c) low level of C
d) low level of E
e) unpredictable - depends on whcih is the inducer molecule
2) if the operon is *repressible*, the maximum level of the enzymes for A-->K is most likely made when there is:
a) high level of C
b) high level of E
c) low level of C
d) low level of E
e) unpredictable - depends on whcih is the co-repressor molecule
The operon model is considered as a cluster of functional genes that are activated in response to stimuli from the environment. An operon is comprised of multiple genes, a promotor, and an operator.
