Control of Gene Expression I
This is the lncRNA that facilitates X-inactivation.
What is Xist?
Most transcription regulators bind to this part of the DNA helix.
What is the major groove?
This type of lipid head group is found on the cytosolic side of the membrane and has a ring structure that lipid kinases modify to recruit proteins to the membrane.
What is phosphatidylinositol?
The equilibrium potential is calculated by using this equation.
What is the Nernst Equation?
When the repressor and CAP protein are bound to the Lac Operon, these two things are missing in the environment.
What are glucose and lactose?
This is the ability to alter gene expression in response to external and environmental signals.
What is dynamic adaptability?
Fluorescence recovery after photobleaching (FRAP) is used to measure the rate of this type of diffusion.
What is lateral diffusion?
This substance does NOT require a protein carrier to cross the cell membrane.
What is nitric oxide (NO)?
This type of RNA has multiple functions, one of the most important being protecting the germ line from transposons.
What is Piwi-interacting RNA (piRNA)?
These are proteins that activate or repress transcription of DNA.
What are transcription regulators?
This is the main component of the red blood cell cytoskeleton that helps maintain structural integrity and shape of the plasma membrane.
What is spectrin?
The flow of any inorganic ion through a membrane channel is driven by this.
What is the electrochemical gradient?
This causes the condensation/coiling of DNA on nucleosomes.
What is the methylation of histones?
Transposons can be dangerous to the germline, causing harmful mutations by inserting themselves into the germline DNA during this process.
What is gametogenesis?
This can be lipid-lipid, lipid-protein, or protein-protein in the membrane.
What is a raft?
This is crucial for glucose recovery from the extracellular medium, when glucose levels are higher in the cytosol than extracellularly.
What is GLUT1?
The stress hormones that are released and can cause dramatic changes in a specific cell’s gene expression.
What are glucocorticoids?
This is defined by an efficient silencing of genes on one of the two X chromosomes in each cell of the female early in development.
What is X-chromosome inactivation (XCI)?
This phospholipid has four fatty acid tails and is involved in several mitochondrial processes, including energy production, membrane stability, and apoptosis.
What is cardiolipin?
This results in impaired chloride transport across epithelial membranes.
What is the misfolding of the CFTR protein?
