A three point test cross was carried out in Drosophila melanogaster involving three adjacent incomplete link genes A, C and B arranged in the same order. The distance between A to C is 20 map units (mu) and that between B to C is 10 map. If pure line Drosophila AAbbCC crosses with aaBBcc to produce F1 offspring were allowed to cross with aabbcc result in 1000 offspring, which of the following genotype combination with number is correct?

Genotype	Number
I- Aabbcc	a- 90
II- aabbCc	b-40
III- AaBbCc	c-10

Many bacterial responses are controlled by two component regulatory systems. What will happen at the high concentration of glutamine and at the low concentration of glutamine?

a) At high concentrations glutamine binds to a sensor domain of NtrB conformational change in the protein that inhibits its histidine kinase activity

b) NtrC phosphorylation takes place causes a conformational change in NtrC that unmasks the NtrC DNA-binding domain so that it can bind to the glnA enhancers

c) At the same time, the regulatory domain of NtrC blocks its DNA-binding domain from binding the glnA enhancers

d) At low concentrations of glutamine dissociates from the sensor domain in the NtrB protein, leading to activation of a histidine kinase transmitter domain
