Paracrine, local, synaptic
Reception, transduction, and cell response
Reception, cell response, cell division
Alpha, beta, and gamma stages
Involves activation of glycogen breakdown in liver cells
Is a classic example of paracrine signaling
Is a classic example of synaptic signaling
Operates independently of receptors on the cell surface
None of these decribes the epinephrine system
After the target cell divides
When the hormone is released into the blood
When the signal molecule changes the receptor protien in some way
After the third stage of cell signaling is completed
None of these show the start of signal transduction
Binds to calcium ions
Lowers blood glucose by binding to cells
Interacts with insulin inside muscle cells
Does not interact directly with glycogen phosphorylase
Never enter the ctyosol of the cell
Are water soluable
Can't pass through the plasma membrane
None of these are correct
All of the above apply to most signal molecules
Activate the kinase domain after they form dimers
Activate the kinase domain before they form dimers
Activate the G-protien that stimulates second messenger production
Are not capable of hydrolyzing ATP
Would not be able to transmit nerve inpulse via a synapse
Could not convert GTP to ATP
Would lack membrane bound receptors
Would not respond properly to epinephrine signals
A signal molecule binds to a membrane receptor protien
Protien Kinase is activated
ATP donates a phosphate group to an inactive protien kinase
A specific protien is activated via phosphorylation
All the above are part of the phosphorylation cascade
Cell signaling was an early event in the evolution of life.
Communicating cells may be close together or far apart.
Most receptor molecules are bound to the outer membrane of the nuclear envelope.
Protien phosphorylation is a major mechanism of signal transduction.
Cytokinesis does not occur
Genes are not duplicated
No spindle forms
DNA replication does not occur
It depends on the specific organism
In the cytoplasm
In the nucleous
On a Chromatid
In a ribosome
Have one-half the amount of DNA as does the original G1 Chromosome
Move together toward one pole of the cell
Are connected at a region called the centromere
Are coiled or uncondensed
When a cell stops metabolizing when it contacts another one in a cell culture.
When a cell stops dividing when it contacts others in a cell culture
When a girl slaps a boy because he touched her
None of hte above describes contact inhibition
Can't tell- need more information
Crossing over between nonsister chromatids
Random fertilization of gametes
Independant assortment of chromasomes
All of the above are involved
Have identical genes
Have genes for the same traits at the same loci
Pair up in prophase II
Are found in all haploid cells
Mitosis occurs only in the gonads
Crossing over happens only in mitosis
Duplicated chromosomes synapse with homologues in meiosis
The nuclear membrane does not fragment in meiosis
Sister chromatids separate
Homologous chromosomes separate
DNA replication precedes the division
They both occur in somatic cells
The gene has more that 2 alleles
The unknown parent was heterozygous
The unknown parent was homozygous
Alleles segregated independently
Can be determined as the product of probablities for each specific genotype
Can be determined from the genotype ratio of that specific cross
Will depend on the genotypes of the parents
All laws of prbability do not affect genotypes.
There is a one in four chance that a gamete with get a dominant allele
Gene pairs segregate independantly of each other.
Allele pairs segregate during gamete formation.
The laws of probability do not affect genotypes.
Can't be determined.
Only females can show the trait
Females can never show the trait
Males more frequently show the trait
The gene is on an autosome
Violate the law of independent assortment
Are on the same chromosome
Support the law of independent assortment
A and B
A and C
The genesare tightly linked
The genes are effectively unlinked
Crossing over hass occured
The genes are 25 map units apart
Only the canary and cockroachwould work
The canary and roach won't work, but you could make a rhino-canary.
You're stuck because all three of them are males.
You could do the rhino-roach and the canary-roach, but not the rhino-canary.
