Topic 8
site in an x chromosome at which inactivation is initiated and spreads outward
what is x-inactivation center?
Divides the genome independently regulated domains and prevent cis-regulatory sequences from expressing the wrong gene
what is an insulator?
what is a uniporter?
what is voltage gated Na+ channels?
small region of the plasma membrane enriched in sphingolipids and cholesterol
what is a lipid raft?
A segment of DNA that is transcribed into RNA, along with control mechanisms.
What is a gene?
Production of a functional RNA by insertion or alteration of individual nucleotides in an RNA transcript after it has been synthesized
What is RNA editing?
This is the building block of the lipid bilayer
What are Phospholipids?
These two types of membrane proteins transport solutes across the cell membrane by forming a hydrophilic protein pathway.
What are transporters and channels?
This small noncoding RNA is known to regulate at least 50% of human protein coding genes
What are microRNAs (miRNA)?
In a bacterial chromosome, a group of contiguous genes that are transcribed from a single promoter into a single mRNA molecule.
What is an operon?
What is methylation of histones?
The direction glycolipids face with respect to the cytosol
What is away from?
This type of transporter found in eukaryotic cells, have the ability to pump hydrophobic drugs out of the cytosol.
What is an ABC transporter?
This is a synthetic spherical lipid bilayer
What is a liposome?
Binding of regulatory sequences to DNA provide this and it is known as the most tight and specific in molecular biology.
What is sequence-specific molecular recognition?
A regulatory event that occurs after RNA polymerase has bound the promoter and commenced RNA synthesis
what is post-transcriptional control?
The formation alpha helices or beta sheets take when they cross the membrane several times
What is a barrel?
These mechanically activated cells made up of the PCDH15 gene trigger an electrical response when stimulated by the tectorial membrane.
What are hair cells?
This protein functions as a light-activated H+ pump that transfers H+ out of archaeal cells
What is bacteriorhodopsin?
These similarities of gene control are found in both eukaryotic and prokaryotic cells.
What are cis-regulatory sequences, activators/repressors that control transcription, and looping.
Phosphorylation of a translation initiation factor to prevent exchange of GDP for GTP.
what is translational control of elF2
The molecule that the cytoskeleton in human red blood cells are comprised of.
What is Spectrin?
Most neurotransmitters bind to this G-protein coupled receptor along with acetylcholine, glutamate, and GABA.
What are metabotropic receptors?
This technique bleaches cell membranes to test the lateral diffusion rates of membrane proteins
What is fluorescence recovery after photobleaching (FRAP)?
