What is a chromosome?

Explanation:
Chromosome is a threadlike, gene-carrying structure located in the cell nucleus. It is formed from DNA wrapped around histone proteins and condenses during cell division so that genetic material can be accurately distributed to daughter cells. Each chromosome contains many genes in a specific order, and the complete set of an organism's chromosomes constitutes its genome. In humans, there are 46 chromosomes (23 pairs). Other options mix up concepts: a gene is a specific DNA segment that codes for a trait; the genome is all genetic material in an organism; DNA is the genetic material itself, whereas a chromosome is the organized structure made of DNA and proteins.
