Topic 1_Introduction to Cells and Biochemistry
The complete organization of hereditary information using DNA
What is a genome
A simple structure that connects two antiparallel strands of DNA
What is Beta Pin Motif?
Another name for a ligand
What is an Antigen?
This elongation factor helps in the translocation of the small subunit to realign the E, P and A sites so that they are ready for the binding of the next amino acetylated tRNA.
What is EF-G?
Provides structure, channels/transport, mobility, enzymes and signaling molecules to the cell
What are proteins
This example of secondary structure has amphiphilic properties that allow the protein to interface with both hydrophobic and hydrophilic environments.
What is alpha helix?
The concentration of bound and unbound substrates is determined by
What is the affinity that a protein has for its ligand?
Structural unit of the eukaryotic chromosome resembling "beads on a string"
What are Nucleosomes?
Two or more genes break and rearrange themselves resulting in a hybrid of the preexisting new gene
What is DNA segment shuffling
An incomplete source of protein that forms a triple helix and only found in animals, around the connecting tissue.
What is Collagen?
A class of proteins that perform a specific function and catalyze a reaction
What is an enzyme?
This structure will determine the properties of the protein and how the protein folds
What is a side chain
The energy that is contained in molecules that is available to do work; measured in ΔG
What is Gibbs Free energy
A type of irregular coils found in ligament and blood vessels with a hydrophobic property that gives its elasticity.
What is Elastin?
This object has two structural domains with one being mostly alpha helices and the other being mostly beta sheets
What is a lysozyme?
This metabolic process breaks down ordered structures to generate energy and small building bocks for cellular biosynthesis
Macromolecules can be disassembled by inserting water between subunits; requires enzymes & is energetically favorable
What is Hydrolysis
An example of multiple peptide chains formed by the interaction between two nonidentical binding sites on each monomer.
what is a tetramer?
This bond is formed by a dehydration synthesis reaction
What is a peptide?
Modifications to this rRNA include about 100 isomerization's of uridine to pseudo uridine and about 100 methylations on the 2' of ribose sugars
What is 45S?
