Which of the following is NOT a function of the CCD camera in cytogenetics?

In the context of cytogenetics, the functions of a charge-coupled device (CCD) camera are primarily related to image capture and processing. The correct answer identifies that modifying the sample’s physical structure is not a function of the CCD camera.

CCD cameras are designed to capture light and convert it into an electronic signal, which is used to create an image. They help control the resolution of the image by determining the level of detail that can be achieved based on the number of pixels in the sensor, also referred to as photo cells. Moreover, these cameras are instrumental in determining the matrix size by using the arrangement and number of photo cells to define the dimensions of the digital image they produce.

However, a CCD camera does not have the capability to alter or modify the sample itself. Its role is strictly focused on capturing the image and relaying that information for analysis, which is why the option that suggests modifying the sample’s physical structure is not accurate. This distinction emphasizes the operational boundaries and specific functionalities of CCD technology in the context of cytogenetic analysis.
