Cell Cycle
There are this many major checkpoints in the cell cycle.
What is three?
RB as mentioned before, is a tumor suppressor. What will occur if a loss of function mutation occurs in one of its alleles?
What is it will still work and not promote cancer?
Nearly all plant organs are formed during this time.
What is post-embryonically?
This is released from the vesicles of the presynaptic neuron?
What is neurotransmitter?
Steroid hormone receptors are located here.
Phosphorylated RB causes what to happen?
What is E2F and DP become active and will drive transcription of genes for the S phase?
MAPKK cannot be inactivated. The side effects from this can be treated by targeting this.
What is MAPK?
Gene B is now being expressed in whorl 1. This results in what organ formation?
What is petals?
One Neurotransmitter-gated Na+ channel is opened on the on the dendrite of the post-synaptic cell. Will this generate an action potential?
What is no?
A fly tastes like a female of the same species and smells like she has not been previously mated. The P1 neuron is...
What is activated?
A neuron has a methylated DNA pol III gene. The cell is in what part of it's lifecycle?
What is G0?
A Hypo-methylated oncogene is the same as what?
What is a gain of function mutation?
This is the reason we do not see A in whorl 4, even though the gene is there.
What is a C protein causes an miR172 gene to be expressed?
The transporter for a neuron into the pre-synaptic cell has an increase in activity. This results in what?
It is more difficult to trigger an action potential?
Epinephrine is released in seconds after being signaled. The type of hormone epinephrine is.
What is amine hormone?
MPF is a cyclin-CDK complex that drives the cell through this checkpoint.
What is the G2/M checkpoint?
Most cancers arise with no genetic predisposition. What happens when an individual has a homozygous mutation for BRCA-1?
What is the mutant is lethal?
A plant has a B mutant. The resulting organ types are...
What is sepal, sepal, carpel, carpel?
The pituitary makes LH and FSH. This then causes the ovary to make estrogen. The estrogen then signals to the pituitary to stop making LH and FSH. This is an example of what type of feedback?
What is a negative feedback?
This type of synapse has direct cytoplasmic connections.
What is electrical synapse?
The protein with the sequence Ala-Gly-Glu-Arg-Leu will be degraded by this enzyme when properly tagged.
What is a proteasome?
K-ras being permanently locked into an active state is an example of a what type of mutation to an oncogene.
What is a gain of function mutation?
The K+ leak channel is blocked. This does what to the resting membrane potential?
What is increase?
A non-competitive antagonist blocks the ability for a neurotransmitter to block a neurotransmitter gated Cl channel. This will result in what happening to the neuron.
The release of cortisol results in what responses from its targeted tissues. (Hint: there are 5)
What is gluconeogenesis, lipolysis, suppress inflammation, brain awareness, memory?
