Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

WRKY plant-specific group of transcription factors that play important role in many plant metabolic and developmental processes such as;

a) It contain a 30 amino acid region named for the conserved amino acid sequence WRKYGQK in its N-terminal domain

b) It is an important regulators of plant–pathogen interactions as well as senescence

c) WRKY53 is involved in the regulation of dark-induced leaf senescence

d) In Arabidopsis, leaf senescence is delayed in knockout mutants of the WRKY53 gene

e) WRKY53 also binds to the promoter of the WRKY53 gene, inhibiting its own expression in a negative feedback loop

Which of the following given prediction about WRKY transcription factor is correct?
