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

#Unit 8. Inheritance Biology

In a transduction experiment, phage P1 is grown on a bacterial host of genotype A+ B+ C+ and the resulting lysate is used to infect a recipient strain of genotype A– B– C–. The genes are in an order such that B is in the middle, and the distance between A and B is greater than the distance between B and C. Based on this information, which of the following least genotype?

In the mating Hfr met- his+ leu+ trp+ × F- met+ his- leu- trp-.  The met marker is known to be transferred very late. After a short time, the mating cells are interrupted and the cell suspensions plated on four different growth media. The amino acids in the growth media and the number of colonies observed on each are as follows:

histidine + tryptophan  250 colonies

histidine + leucine         50 colonies 

leucine + tryptophan    500 colonies

histidine                       10 colonies
