Question

Suppose protein C functions as a homodimer, where the two subunits can be identical (C1C1 or C2C2) or slightly different (C1C2). Further suppose that the C1C2 version is more stable than either homodimer with identical subunits. Heterozygous individuals would then have an advantage due to?

1) Increased stability of the C1C2 version
2) Decreased stability of the C1C2 version
3) No advantage
4) Cannot be determined

Answer 1

Heterozygous individuals have an advantage due to the increased stability of the C1C2 version of protein C.

Step-by-step explanation:

The advantage for heterozygous individuals in this case would be the increased stability of the C1C2 version of protein C. The question states that the C1C2 version is more stable than either homodimer with identical subunits. Therefore, heterozygous individuals who have both C1 and C2 subunits would have a more stable protein compared to homozygous individuals who have either C1C1 or C2C2 subunits.
