What is the organization of DNA within a chromosome?
Chromosome Structure
Chromosome structure includes the arrangement of DNA and its associated proteins.
What is the primary function of chromosomes?
To store and transmit genetic information
Chromosomes ensure DNA is accurately replicated and distributed during cell division.
