26-residue peptide composed of alanine and leucine shows a circular dichroism (CD) spectrum characteristic of α-helix at 50°C in 5 mM phosphate buffer at pH 7.4. When the peptide solution is cooled gradually to 25°C, and the CD spectra are recorded at different temperatures, the most likely observation will be that

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.
