During an ethylene signalling pathway, what will have done  inside cytosol and nucleus . Given below some prediction about presence and absence of ethylene in column B match with column A

            COLUMN A

                                           COLUMN B

I-  In the presence of ethylene

a)  ETR1 signaling is repressed and CTR1 is inactive

II- In the absence of ethylene

b)  ETR1 activate CTR1, a Ser/Thr kinase

 

c)  CTR1 phosphorylates the C-terminal domain of EIN2

 

d)  The nonphosphorylated C terminus of EIN2 is cleaved by a protease

 

e)  Phosphorylation of EIN2 inhibits proteolytic cleavage

 

f)  EIN3 transcription factors are ubiquitinated and degraded in the nucleus by the 26S proteasome

 

g)  EIN3 initiates a transcriptional cascade by activating expression of ethylene-responsive genes, including ERF1 transcription factor, leading to ethylene responses

Two trains are running on parallel lines in the same direction at speeds of 60 km/h and 35 km/h respectively. The faster train crosses a man in the slower train in 54 second. If the length of the slower train is 4/5th of the faster train, find the length of the slower train.

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 
You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.
