How to identify Ribose from Deoxyribose?
Ribose has an OH group, Deoxyribose does not have an OH group, only H.
What is nucleoside composed of?
Sugar and a Base
This is an example of
Nucleoside
This is an example of ?
Nucleotide
What is the difference between a nucloside and a nucleotide?
Nucloside contain sugar and a base and a Nucleotides have a Phosphate group attach to a nucloside
How do you name Nucleosides and Nucleotide?
1) Drop ine or osine
2) Purines ends with osine
3) Pyramiding ends with iodine
4) If it is DNA nucleoside add deoxygenated at the beginning

Of the three basic parts of cell communication, which part is always protein-based?
receptor
secondary messenger
chemical messenger
Receptor
Adrengeric
Adrengeric
Peptidergic
Steriod
Is this a DNA nucleotide or RNA nucleotide?
RNA nucleotide
This is an RNA nucleotide composed of ribose, a phosphate, and either uracil, cytosine, adenine, or guanine. DNA nucleotides contain deoxyribose, which does not have a hydroxyl group on the second carbon of the sugar ring.
DNA nucleotide

DNA Polymerase
Joins the Okazaki fragments
DNA Ligase
Transfer RNA
Transports amino acids to site of protein Synthesis (Ribosomes)
Ribosomal RNA
ribosomes, the site of protein synthesis
Messenger RNA (MRNA)
Directs/carries amino acid sequence of proteins for processing
