#6. System Physiology – Plant
  1. Phytochrome in the functionally active dimeric form with a molecular mass of about 250 kDa
  2. phytochrome chromophore is a linear tetrapyrrole and absorbed light called phytochromobilin
  3. Phytochromobilin is exported  to the cytosol where it autocatalytically attaches to the PHY apoprotein through a thioether linkage to a cysteine residue
  4. Phytochromobilin undergoes to the cis and trans isomerisation with its pyrrole ring around C-12 and C-13 after absorbing light

#8. Inheritance Biology

Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aabbcc) is 10 cm in height. The other strain (AABBCC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce 1000 F2 progeny. what is number of F2 progeny having intermediate height?
