Answer:
DNA is a double stranded molecule that belongs to a group of larger molecules (macromolecules) called NUCLEIC ACIDS.
Nucleic acids are formed by joining together many smaller molecules called NUCLEOTIDES.
Nucleotides consist of:
- Pentose sugar (pentagon)
- Phosphate group (circle)
- Nitrogenous (rectangle)
Two features that Eukaryotic cells have and prokaryotic cells lack:
1) Nucleus
2) Nuclear bound organelles like chloroplasts, Mitochondria, Golgi appratus etc
