Base Pairing
100
DNA stands for... (say it slow to make sure all parts are said)
What is Deoxyribonucleic Acid?
100
There were found to be 4 nitrogenous bases. Adenine, thymine, guanine, and THIS
What is Cytosine?

Spell the Nitrogenous base that starts with G
G-U-A-N-I-N-E

This is the Norse event that marks the end of the world. Also the sub title of the new Thor movie.
What is Ragnarok?

2. List the chemical components of DNA
Phosphate group, Sugar (deoxyribose), Nitrogenous Base
200
DNA is this type of acid, meaning it is found in a particular part of a cell
What is Nucleic Acid?
200
Erwin _____ found that levels of A equaled T, and levels of G equaled C, which later had a rule named after him.
What is Chargraff?
200
Spell the last name of the scientist that found A=T and C=G.
C-H-A-R-G-R-A-F-F
200
This astronaut was the first person to walk on the Moon.
Who is Neil Armstrong?
300
3. Why are hydrogen bonds so important to the structure of DNA?
Hold together the paired bases. Bonds are weak, the two strands can be easily separated to perform the important functions of DNA
300
DNA is a type of acid that is made of THESE "building blocks"...
What is nucleotides?
300
This doctor used X-rays to discover the shape of DNA. This paved the way for all other people's discoveries about DNA.
Who is Dr. Rosalind Franklin?
300
Spell the type of bases found in DNA
N-I-T-R-O-G-E-N-O-U-S
300
This U.S. president founded the University of Virginia in 1819.
Who is Thomas Jefferson?
400
4. Describe the discoveries that led to the modeling of DNA. (For game points - just name the 4 last names of the people)
1)Chargraff - A=T, C=G 2)Franklin - DNA shaped like double Helix 3)Watson & Crick - structure of DNA
400
This is the type of bases in DNA
What is Nitrogenous?
400
These two scientists solved the structure of DNA after reading about the shape of DNA from another scientist
Who are Watson and Crick?
400
Spell the sugar found in DNA
D-E-O-X-Y-R-I-B-O-S-E
400
This famous nerd was an inventor, botanist, sculptor, architect, musician, scientist, mathematician, writer, historian, etc. Also, he painted a woman that doesn't smile, and sketched a man that shows the proper proportions of a human.
Who is Leonardo da Vinci?
500
5. Describe Watson and Crick's model of the DNA molecule.
A)Antiparallel strands: Each side runs in opposite directions. B)Hydrogen bonds: connect nitrogenous bases C)Base pairing: only bonds between A-T and C-G
500
This is the 5-carbon sugar in DNA
What is deoxyribose?
500
The scientists that solved the structure also solved that THESE held base pairs together. They are weak bonds that allow DNA to be pulled apart to perform its important functions.
What is Hydrogen Bonds?
500
Spell the first name of the scientist that used X-rays to learn the shape of DNA
R-O-S-A-L-I-N-D
