The structural maintenance of chromosome (SMC) proteins are extended proteins that form defined pairs by interacting through lengthy coiled-coil domains. Together with non-SMC proteins, they form multiprotein complexes that act to link two DNA helices together. Identify the SMC proteins in the figure given below and match them with their respective subunits.

i. Blue – Cohesin made up of Smc 1 and Smc 2 proteins.

ii. Green – Condensin made up of Smc 3 and Smc 4 proteins.

iii. Blue – Condensin made up of Smc 2 and Smc 4 proteins.

iv. Green – Cohesins made up of Smc 1 and Smc 3 proteins.

v. Blue – Condensin made up of Smc 1 and Smc 3 proteins.

vi. Green – Cohesins made up of Smc 2 and Smc 4 proteins.

Wild type E. coli metabolizes the sugar lactose by expressing the enzyme ß-galactosidase. You have isolated a mutant that you call lac1–, which cannot synthesize ß-galactosidase and cannot grow on lactose (Lac–). During an condition you have a wild type (Lac+) strain carrying a Tn5 insertion known to be near several Lac genes on the E. coli chromosome. You grow P1 phage on this strain and use the resulting phage lysate to infect the lac1– strain, selecting for kanamycin resistance (Kanr). Among 100 Kanr transductants, you find that 82 are Lac– and 18 are Lac+. Express the distance between Tn5 and the lac1– mutation as a cotransduction frequency;
