Final answer:
Gel electrophoresis is used to isolate components in histones by separating them based on size and charge. The option (C) is correct.
Step-by-step explanation:
Gel electrophoresis can be used to isolate components in histones. In gel electrophoresis, samples are pipetted into wells of a gel, and an electric field is applied.
The components in histones will move through the gel at different speeds based on their size and charge, allowing for their separation. Through comparison with standards, the separated components can be visualized and identified. Therefore, option (C) is correct.
