What is the fundamental process of information transfer in cells?
The use of DNA and RNA.
What are the two ring systems used in nucleotides? What are the sizes of the rings?
Pyrimidine: 6 member ring
Purine: 6 member ring and 5 member ring.
Which nucleotides come from the pyrimidine rings?
Cytosine, Uracil, Thymine
Which nucleotides come from the purine rings?
Adenine and Guanine.
What is the difference between a nucleoside and a nucleotide?
Nucleoside: Base + Sugar
Nucleotide: Base + Sugar + Phosphate
What are the components of a nucleotide?
The purine or pyrimidine base linked to a ribose or de-oxy ribose sugar with a phosphate group attached to the sugar.
What are the 2 pathways to build nucleotides?
The De novo pathway and the Salvage pathway.
What are the main ideas behind the de novo pathway?
1. begins with metabolic precursors (aa's, ribose 5 phosphate, and CO2)
2. The free bases (A, T, G, C, and U) aren't intermediates.
3. Present and identical in nearly all living organisms.
What are the main ideas behind the salvage pathway?
1. The free bases and nucleosides released from nucleic acid breakdown are recycled.
2. The free bases (A, T, G, C, and U) are intermediates.
What are the sources of the atoms in the Purine ring?
Aspartate, CO2, Glycine, Formate, and the Amide N of glutamine.
