What does DNA stand for ?
|
Deoxyribonucleic Acid
|
|
|
What does RNA stand for ?
|
Ribonucleic Acid
|
|
|
what are nucleotides?
|
Polymers of repeating units in both DNA and RNA
|
|
|
What are the 3 parts all nucleotides have?
|
1. Phosphate
2. Pentose (5 carbon) sugar 3. A nitrogen base (A,T,C,G) |
|
|
What are the differences between DNA and RNA?
|
1. Sugar- deoxyribose is missing an Oxygen in the spot where Ribose contains a hydroxyl group.
2. Base- DNA contains all nitrogen bases except Uracil, RNA contains all nitrogen bases except Thymine 3. RNA is single stranded, DNA is double stranded and double helix |
|
|
Ribonucleotides-
|
-nitrogen base adenine, guanin, cytosine, and uracil
- connected to ribose with 1-3 phosphates on 5th carbon |
|
|
Deoxyribonucleotides-
|
-nitrogen base adenine, guanine, cytosine, and thymine.
- connected to deoxyribose, no OH on 2nd carbon with 1-3 phosphates |
