Are genes many chromosomes joined together?

Explanation:
Genes are units of heredity made of DNA. They reside on chromosomes, which are single, long DNA molecules wrapped with proteins inside the cell nucleus. The idea that genes are formed by joining many chromosomes isn’t correct—each chromosome carries many genes along its length, and cells contain multiple chromosomes. Some genetic material is in mitochondria, but most genes are located on nuclear chromosomes, not exclusively there. And genes are made of nucleotides in DNA (not lipids). So the statement is false.
