What does DNA stand for?
Deoxyribose Nucleic Acid
Who was the unsung hero of the discovery of the double helix?
Rosalind Franklin
Why is our DNA important?
- genetic blueprint/map for every organism
- makes us us!
Provides the blueprint for the contraction and maintenance of every single cell
Who were the three male scientists who took credit for the discovery of the double helix?
Watson, Crick, Wilkins
What are building blocks of DNA? draw a model and label each part
nucleotides (see image) made of phosphate group, 5 carbon sugar, and a base pair
How does DNA's structure allow it to perform its function?
Double helix: stores lots of info in a compact way
Complementary base pairs and H bonds; allow for easy replication
Adenine & Thymine - two hydrogen bonds
Guanine & Cytosine - three hydrogen bonds
- H bonds are easy to break apart for replication- Complementary base pairs allow for one side of DNA to act as blueprint in semiconservative replication process
What kind of macromolecule helps with DNA replication?
ENZYMES = PROTEINS! --> helicase, DNA polymerase, ligase, etc.
Draw the molecular model of DNA with the code ATTACGCTA
see images - must include each nucleotide, the correct pairing, a 5' and 3' end, antiparallel strands
what is the enzyme responsible for unzipping the DNA during replication?
helicase
