Chromosomes and DNA Replication

2. Chromosome Structure
Eukaryotic chromosomes contain both DNA and protein, tightly packed together to form a substance called chromatin
The protein is called a histone

New nucleotides fill in the space to form new strands
Each strand is completely filled in to form two identical strands of DNA

5. DNA Polymerase
DNA polymerase is the main enzyme involved in DNA replication
