Protein Alignment and Analysis Quiz

What is the primary focus of protein alignment in this tutorial?

• Analyzing protein sequences

• Comparing different species

• Studying protein synthesis

• Aligning similar proteins or proteins in different conformations

What is the first step in visualizing the protein 2qcs in PyMOL?

• Removing the regulatory subunit

• Aligning the protein

• Fetching the PDB code

• Coloring the protein

Which subunit is removed to focus on the regulatory subunit in 2qcs?

• Regulatory subunit

• Structural subunit

• Catalytic subunit

• Binding subunit

What color is used to display the protein 1RGS in PyMOL?

• Ocean blue

• Fire brick

• Deep teal

• Bright yellow

What is the initial result of aligning the entire proteins 2qcs and 1RGS?

• Partial alignment

• No alignment

• Perfect alignment

• Poor alignment with many yellow lines

How is the alignment improved in the tutorial?

• By aligning the entire protein

• By focusing on specific residues

• By changing the color of the protein

• By removing all subunits

Which residues are selected for improved alignment?

• 113 to 160

• 50 to 100

• 1 to 50

• 200 to 250

What is the main observation after aligning specific residues?

• No change in alignment

• Complete misalignment

• Worse alignment

• Improved alignment with fewer yellow lines

What causes the large conformational change in the protein?

• Temperature change

• Protein synthesis

• Lian binding

• pH change
