The following scheme shows the flowering status of a plant species and the photoperiodism. Which of the following conclusions is most appropriate?

#I Life Science/ Life Sciences Group – I-V
  1. The species is a short day plant; length of the dark phase determines flowering status.
  2. The species is a long day plant; length of the dark phase determines flowering status.
  3. The species is a short day plant; length of the light phase determines flowering status.
  4. The species is a long day plant; length of the light phase determines flowering status.

#SCPH01 Biochemistry

PCR efficiency is influenced by several factors, the efficiency declines due to
a) efficiency of amplification declines with an increase in the length of the target sequence.
b) Efficiency of PCR is affected by primer length; it declines if the primers used for PCR arc too long.
c) a temperature higher than the ideal annealing temperature reduces PCR efficiency.
d)  primers used for PCR have complementary regions, dimers will be formed, and PCR efficiency will decline.
