Short explain and type please
What is the daf-2 gene and how did a mutation to this gene affect C elegans? Could a mutation to this gene affect humans the same way? Explain.
Homework Answers
Daf 2 gene is only gene that encodes insulin like growth factor is c.elegans. these are responsible for regulating metabolic pathway and rate of aging. These regulate reproductive developmental processes and resistance to oxudative stress .disabling in daf2 gene lead to enter c.elegan into diauper stage so increase the longeivity delays senescence and reproductive maturity. So mutation in daf2 gene lead to extended life span in c.elegans. but in humans it affect multiple pathways not just single pathway growth as well as it is lower in old age and in infancy. In humans also it retard reproductive maturity.

Let's say that a human is homozygous for a mutation in the IRE-BP gene that changed the structure of the iron regulatory protein in such a way that it could not bind iron, but still could bind to mRNA. How would this mutation affect the regulation of the transferrin receptor mRNAS ? A.It would cause the transferrin receptor gene to always be expressed B.It would prevent the transferrin receptor gene from being expressed C.It would cause iron to increase inside...

Please answer 2-5
2. Consider a gene with a particular function. Mutation X and mutation Y cach cause defects in the function of the encoded protein, yet a gene containing both mutations X and Y encodes a protein that works even better than the original protein. The odds are exceedingly small that a single mutational event will generate both mutations X and Y. Explain a simple way that an organism with a mutant gene containing both mutations X and Y...

Q15 8 Points In C. elegans, a protein encoded by the gene odr-4 is required to transport the protein ODR-10 to the cell membrane of the worms' sensory neurons. As described in HW7, ODR-10 detects the molecule diacetyl, which is secreted by the worms' bacterial food source. What would happen to the animals' ability to detect diacetyl if there was a mutation in the odr-4 gene that inactivated it? (One sentence) Why (one sentence)? Enter your...
