Based on Figure 21.4 and its caption, which statement is TRUE regarding the protein interaction map in Saccharomyces cerevisiae?
A: The white dots on the map represent proteins whose functions have been fully assigned to one of the 13 cellular categories.
B: The expanded area of the map, highlighted with blue dots, specifically details gene products primarily involved in DNA replication and repair.
C: The global map shows interactions (lines) among approximately 4,500 gene products (dots), where dots of the same color belong to one of 13 cellular functions.
D: The map exclusively displays gene products related to protein folding and glycosylation, with no unassigned proteins.
Explanation
Figure 21.4's caption explicitly states it shows 'interactions lines among about 4,500 gene products dots in Saccharomyces cerevisiae' and that 'Dots of the same color represent gene products involved in one of the 13 similarly colored cellular functions.' It also mentions 'The white dots represent proteins that haven't been assigned'.
