Question

prelab questions:

1. what does dna stand for?
2. what are the monomers of dna?
3. what are the 4 bases in dna?
4. what is the shape of dna called?
5. why cant you see a single strand of dna today?
6. why are we using strawberries for this lab?

Explanation:

1. DNA stands for Deoxyribonucleic Acid.
2. The monomers of DNA are nucleotides.
3. The 4 bases in DNA are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
4. The shape of DNA is called a double - helix.
5. We can't see a single strand of DNA today because DNA strands are extremely small and require specialized equipment like electron microscopes to visualize individual strands.
6. We are using strawberries for this lab because strawberries are octoploid (have 8 copies of each chromosome), so they have a relatively large amount of DNA per cell, making it easier to extract and observe compared to diploid organisms.
