Which of the following is NOT true about "Chromosomes"?

Chromosomes are indeed made of DNA, which is organized into genes. Each chromosome consists of a single, long DNA molecule and associated proteins that help package and manage this DNA. They play a crucial role in heredity, as chromosomes are inherited from both parents, ensuring genetic continuity across generations.

Option C states that chromosomes are found in the mitochondria. While it is true that mitochondria contain their own small circular DNA, they do not contain chromosomes in the way that the nucleus of a cell does. The bulk of an organism's genetic material is located in the chromosomes within the cell nucleus, not in the mitochondria. This distinction makes option C the correct answer, as it describes an incorrect characteristic of chromosomes.
