Adenine, Guanine, Cytosine, and Thymine
What are the nitrogenous bases of DNA?
|
They are used to measure very small volumes starting at 1 microliter
What are micropipettes used for?

2
How many bonds can oxygen form?
|
Code for Genes
What does DNA do?
|
3' to 5'
In which direction is DNA read?
|
1000 microliters
How many microliters are in 1mL?
|
Restriction Enzyme
What can be used to cut DNA?
|
Deoxyribose sugar, Phosphate, and the nitrogenous base
What are the three parts of a nucleotide?
|
DNa is double-stranded and RNA is single-stranded
What is the difference between DNA and RNA?
|
Adenine - Thymine
Guanine - Cytosine
Which nitrogenous bases pair to each other?
|
After every use
How often does the pipet tip need to be replaced?
|
The DNA ladder is a set of standards that are used to identify the approximate size of a molecule run on a gel.
What is the DNA ladder used for?
|
Helix
What is the structure of DNA?
|
Thymine is replaced with Uracil
Which base pair(s) is different in RNA than in DNA?
|
Hydrogen bonding
What is the intermolecular interaction that connects DNA strands?
|
Load the restriction enzymes and DNA into the gel
What did we use the micropipettes for during the gel electrophoresis?
|
EcoR1 and Hind (III)
What was one of the restriction enzyme used in today's lab?
|
Pyrimidines: Adenine and Guanine
Purines: Cytosine and Thymine (Uracil in RNA)
Which nitrogenous bases are the purines and which are the pyrimidines?
|
Using X-ray Chrystallography
How did Watson, Crick, and Franklin discover the double helix model?
|
Pentose sugar
What is the ring structure of the deoxyribose sugar?
|
P200
What micropipette was used during today's lab?
|
Exposing the stained gel to a UV light source causes the DNA/dye to fluoresce and become visible.
Why does the gel need to be read under UV light?
|
The hydrogen attached at the carbon 2 position of the deoxyribose sugar is replaced with a hydroxyl group in the ribose sugar
What is the difference between deoxyribose sugar and a ribose sugar?
