#Unit 6. System Physiology – Plant

In Arabidopsis, phot1 mutants have a normal avoidance response and a poor accumulation response, phot2 mutants lack the avoidance response but retain a fairly normal accumulation response, while phot1/phot2 double mutant lack both the avoidance and accumulation responses. These results indicate that,

In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carriers. Has the frequency of allele a changed between Generations 1 and 2?

#Unit 2. Cellular Organization

Match the following lipid linked proteins (column I) with their function (Column II).

Column I	Column II
A. prenylated proteins	i. These proteins are located in a number of subcellular compartments, including the cytosol, the endoplasmic reticulum, the inner face of the plasma membrane, and the nucleus.
B. fatty acylated proteins	ii. The core structure of these proteins consists of phosphatidylinositol glycosidically linked to a linear tetrasaccharide composed of three mannose residues and one glucosaminyl residue.
C. glycosylphosphatidylinositol-linked proteins	iii. The proteins that have covalently attached lipids that are built from isoprene units
