when plastoquinone is accumulates in the reduced state, Reduced plastoquinone accumulates when PSII is being activated more frequently than PSI. What will happen when plastoquinone becomes more oxidized?

#Unit 6. System Physiology – Plant
  1. The kinase is deactivated and the level of phosphorylation of LHCII is decreased by the action of a membrane-bound phosphatase
  2. The kinase is activated and then phosphorylate a specific threonine residue on the surface of LHCII
  3. phosphorylation of LHCII is take place and the phosphorylated LHCII then migrates out of the stacked regions of the membrane into the unstacked regions
  4. kinase is deactivated dephophorylation takes place and LHCII moves back to the stroma lamellae away from photosystem II

#Unit 8. Inheritance Biology

A certain kind of snail can have a right-handed direction of shell coiling (D) or left handed coiling (d). If direction of coiling is due to a protein deposited by the mother in the egg cytoplasm, then a Dd egg-producing snail and a dd sperm-producing snail will have offspring of which genotype(s) and phenotype(s)?

Maternal inheritance of coiling of shell in snail (limnaea peregra) is well established. The dextral coiling depends on dominant allele D and sinistral coiling depends upon recessive allele d. A female F1 progeny of dextral(Dd) type is crossed with a male dextral (Dd). What will be the phenotype ratio in progeny?

In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf),  which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant  is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have
