1
Q
What are the chemical components of DNA?
A
Deoxyribonucleic Acid (DNA) is a nucleic acid made up of nucleotides joined into long strands or chains by covalent bonds.
2
Q
What does the double-helix model tell us about DNA?
A
The double-helix model explains Chargaff’s rule of base pairing and how the two strands of DNA are held together.
3
Q
What clues have helped scientists solve the structure of DNA?
A
The clues in Franklin’s C-ray pattern enabled Watson and Crick to build a model that explained the specific structure and properties of DNA.
4
Q
Base pairing
A
The nearly perfect fit between A-T and G-C nucleotides which hold together the double helix by hydrogen bonding.
