DNA

Question 1

How is DNA stored in eukaryotic cells?

DNA

Answer 1

Contain linear DNA molecules that exist as chromosomes found in nucleus
DNA molecule is very long so is wound around histone proteins which also support the DNA
DNA is coiled very tightly to make compact chromosome
Mitochondria and chloroplasts have own DNA - circular and shorter & not associated with histones

Question 2

How is DNA stored in prokaryotic cells?

DNA

Answer 2

Also carry DNA as chromosomes but DNA molecules are short and circular
No histones - condenses to fit cell by supercoiling
