Topic 1:Cells, Genomes and Diversity of Life
DNA and RNA are composed of these 6 elements
What is oxygen, carbon, hydrogen, sulfur, nitrogen and phosphorus?
Flexible regions that can link structured domains and permit a protein to adopt multiple conformations
What are Intrinsically disordered regions/ Unstructured regions?
This regulatory protein tags other proteins for destruction
What is ubiquitin?
This cellular component possesses its own DNA and is theorized to have originated from a bacterium.
What are mitochondria?
Hydrogen-bonding, polar attractions, van der Waal forces, and hydrophilic-hydrophobic interactions
What holds together a supermolecular assembly?
This family of proteins can walk on a filament via the hydrolysis of ATP
What is a motor protein?
Circular DNA sequence that can replicate independently and insert into the cell's own genome
What is a plasmid?
Leucine, Glutamine, Alanine, Methione, Lysine associate in this structure
Hint Lovely queens always marry kings
What is an alpha- helix?
This type of enzyme performs a phosphorylation reaction
What is a kinase?
2 core functions of the virus genome
What is genome packaging process and nucleic acid replication?
Self-propagating, stable beta sheet aggregates built of identical polypeptide chains, layered on top of each other for forma stack of beta sheets
What are amyloid fibrils?
This binding site on an enzyme can turn it on or off
What is the allosteric site?
Brownian motions drives a process which determines the rates of biochemical reactions as molecules collide with one another within the interior of a cell.
What is diffusion?
A structurally conserved protein domain on the Src oncoprotein present in eukaryotic proteins. It is responds to cell signals to cause certain molecules to bind to each other. This alters cell behavior. Hint: tyrosine kinase
What is SH2 domain?
This equation measures the catalytic efficiency of enzymes
What is kcat/Km?
