, The code for life
• Important for life because it holds the instructions for protein
synthesis and proteins are responsible for determining the structur
and function of an organism
• Nucleic DNA
• MtDNA & DNA in chloroplasts = extranuclear DNA
• DeoxyriboNucleic Acid structure:
• Five carbon, pentagonal sugar (deoxyribose)
• Phosphate group to link sugar onto next phosphate to form a chain
• Nitrogenous base (Adenine, Thymine, Cytosine, Guanine)
