Nucleic Acids Flashcards
Biomolecule Essential to all forms of life
Nucleic Acids
DNA meaning
Deoxyribonucleic Acid
RNA meaning
Ribonucleic Acid
Parts of a Nucleotide
- Pentose Sugar / Ribose Sugar
- Nitrogenous Base
- Phosphate Group
The kind of Pentose present in RNA
Pentose = Sugar
D - Ribose
The kind of Pentose present in DNA
Pentose = Sugar
2-Deoxy-D-Ribose
Purines
Nitrogenous Base
- Adenine
- Guanine
Pyrimidines
Nitrogenous Base (DNA)
- Cytosine
- Thymine
Pyrimidines
Nitrogenous Base (RNA)
- Cytosine
- Uracil
Nucleotide are connected by [BLANK] that link the 3’ Hydroxyl Group of one Nucletide to the 5’ Hydroxyl of another
Phosphodiester Bonds
What is Chargaff’s rule
a 1:1 stoichiometric ratio of purine and pyrimidine bases in the DNA of any species
DNA vs RNA
DNA
* 2-Deoxyribose Sugar
* Double Stranded
* Base Pairs: Adenine, Guanine, Cytosine and Thymine
RNA
* Ribose sugar
* Single stranded
* Base Pairs: Adenine, Guanine, Cytosine and Uracil
Trivia Time! How long is DNA from just one cell
Over a meter long!
DNA from an entire body would reach the moon and back
Second trivia comes from Dr. One!
What proteins is DNA coiled around?
Histones
One long supercoiled DNA with all of the histones
Chromatin
