Answer:
Mutations affecting proteins involved in the ubiquitination pathway
Explanation:
The cyclins represent a group of proteins capable of regulating the progression of the cell cycle via activation of cyclin-dependent kinases (CDKs). Cyclins are degraded by ubiquitination, a posttranslational modification that triggers the exit of mitosis by "marking" cyclin proteins for their subsequent degradation in the proteasome. The proteasome is a macromolecular complex required for the degradation of proteins in the cell. Then consequently the mutations affecting both secondary proteins required during ubiquitination and those involved in the functioning of the proteasome complex might prevent the degradation of cyclin proteins.
Researchers cross a corn plant that is pure-breeding for the dominant traits colored aleurone (C1), full kernel (Sh), and waxy endosperm (Wx) to a pure-breeding plant wiht the reccessive trains colorless aleurone (c1), shrunken kernal (sh), and starchy (wx). The resulting F1 plants were crossed to pure-breeding colorless, shrunken, starchy plants. Counting the kernals from about 30 eats of corn yields the following data:
Kernel Phenotype Number
Colored, shrunken, starchy 116
Colored, full, starchy 601
Colored, full, waxy 2538
Colored, shrunken, waxy 4
Colorless, shrunken, starchy 2708
Colorless, full, starchy 2
Colorless, full, waxy 113
Colorless, shrunken, waxy 626
6708
A) Why are these data consistent with genetic linkage among the three genes?
B) Perform a chi-square test to determine if these data show significant deviation from the expected phenotype distribution.
C) What is the order of these genes in corn?
D) calculate the recombination fraction between the gene pairs.
E) what is the interference value for this data set?
D) #recombinant=116+601+4+2+113+625=1462
#nonrecombinant=2538+2708=5246
RF=R/(N+R)=1462/6708=0.2
E) I=1-Q
I-interference
Q-coefficient of coincidence
Q=O2Xo/E2xo(2xo-double crossovers)
O2xo=6
P=(distance from C1 to Sh/100)*(distance from Sh to Wx/100)
=(3.38/100)*(18.28/100)=0.006
E2xo=0.006*6708=40.248
Q=6/40.248=0.15

Answer:
all of these
Explanation:
Certain molecules like proteins and lipids are synthesized by organnelles in a cell. These molecules are transported by small membrane enclosed sacs in a cell called VESICLES.
Vesicles are small enclosures surrounded by a membrane made of lipid bilayer. This membrane separates them from the cytoplasm of the cell. They function as transport compartments that move particles in and out of the cell.
Vesicles are produced by some organnelles that make-up the Endomembrane system like Endoplasmic Reticulum, Golgi apparatus etc. while other vesicles are created as a result of endocytosis by the cell membrane. Vesicles can serve as secretory vesicles or transport vesicles etc.

The term heterochromatin refers to heavily condensed regions of chromosomes that are largely devoid of genes. Since few genes exist there, these regions almost never decondense for transcription. At what point during the cell cycle would expect to observe decondensation of heterochromatic regions? Why?
Answer:
The correct answer is: S phase.
Explanation:
DNA can be divided into two functional forms: heterochromatin and euchromatin. Heterochromatin refers to the DNA that doesn't code for proteins or RNA, and thus it remains heavily condensed, for there would be no use to use it for transcription or translation. Euchromatin, on the other hand. is the DNA with the genes that can be transcripted into RNA and translated into proteins; for this reason, Euchromatin is less compact than Heterochromatin.
The only point in the cell cycle where Heterochromatin would be decondensed is S phase because, in this part of the cell cycle, the DNA gets replicated in order to prepare for Mitosis. For DNA to be replicated, it first needs to be decondensed to their two strands can be separated and used as guides for the synthesis of the two new strands.
Write down the oxygen requirements of the microorganisms growing in thioglycolate tube.
Answer:
Obligate aerobic microbes requires oxygen for its survival in the thioglycolate tube while Obligate anaerobic microbes does not requires oxygen.
Explanation:
Thioglycolate tube is a tube which is used to determine the oxygen requirement of different types of microbes. The concentration of oxygen is higher in the upper portion of the tube while in the lower portion, the concentration of oxygen is the lowest. So those microbes who needs oxygen for their survival will be present in the upper portion of the tube while those microbes who does not need oxygen, will be present at the bottom of the tube.

In the case of two EPSPs occurring at a single synapse, which of the following will produce a subthreshold effect and not generate an action potential on the postsynaptic neuron’s axon hillock?
a. Both EPSPs occurring in rapid succession
b. The summed EPSPs depolarizing the axon hillock membrane to —70 mV
c. Both EPSPs occurring before the postsynaptic membrane potential returns to —55 mV
d. Both potentials occurring after the postsynaptic membrane potential returns to its resting value
Answer:
Both potentials occurring after the postsynaptic membrane potential returns to its resting value
Explanation:
This is simply because, a neuron returning to its resting state,will have the ligand gated Na+ channels closed.Therefore depolarization can not occur.More K+ gated channels will open, and more K+ leaks out of the axoplasm,returning the neuron to the resting state.
Hence if the summation of the two EPSP returns to the resting level after crossing the synapse, they can not propagate,and generate action potential, because they will produce a sub threshold effects,which will not generate action potential.
a smoker develops damage to several alveoli that can no longer function. how does this affect gas exchange?
Answer:
Smoking causes the hardening of the alveoli walls. This keeps them from extending or stretching out because of the loss of elasticity. In such a circumstance, it is hard to take up oxygen from the inspired air or to remove carbon dioxide from the circulation system. This would prompt partial or less trapping of the gases in the lungs.
With this damage due to smoking, the alveoli can not assist the bronchial tubes enough. The tubes also get damaged and cause a blockage or obstruction, which traps air inside the lungs. An excess of air caught in the lungs can give a few patients a barrel-chested appearance.

Schilders disease is a progressive degeneration of the central nervous system that leads to death by age 2. The disease is caused by a simple autosomal recessive mutation. A couple loses its first two children to Schilders disease. If they decide to have a third child, what is the probability that it will have the disease
Answer:
The probability will be 25% (1/4)
Explanation:
Schilder's syndrome is a degenerative and progressive lethal disease caused by the demyelination of nerve cells in the brain and spinal cord. Since it is a lethal recessive autosomal disease, both the father and the mother have a single copy of the mutant allele, thereby the probability of obtaining a lethal combination will be:

Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: negative feedback first tier of control positive feedback fourth tier of control
Answer:
The correct answer is: positive feedback.
Explanation:
Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance inhibits its producer that is called negative feedback. On the other hand, when a substance stimulates its producer to keep secreting said substance, this is called positive feedback.
Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).
Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.

The cyclin B–Cdc2 complex controls the passage from G2 into M and is assembled before mitosis however, its catalytic activity is restricted to mitosis. What process is responsible for the activation of the cyclin B–Cdc2 complex?
Answer:
Phosphorylases that selectively add phosphate groups to the Cdc-2 subunit, thereby activating this complex.
Explanation:
The cyclin B-Cdc-2 (also known as maturation-promoting factor or simply MPF) complex is activated when it enters into the nucleus during the G2/M transition in the cell cycle. Cdc-2 is a protein kinase that associates with cyclin proteins. These proteins (cyclins) regulate the cell cycle by activating cyclin-dependent kinases. It is well known that phosphorylation of the Cdc2 subunit at different residues can both activate and inactivate the MPF complex. Moreover, enzymes capable of both inactivating phosphorylases and activating phosphatases have also shown to be able to activate MPF.
