I have been doing this problem several times now and I can't figure out how to do it. I am so confused. Can you as well describe the number of chromosomes you get from mitosis?
Explain the changes in clarity and viscosity of a nuclear suspension which takes place on the addition of Sodium Dodecyl Sulfate (SDS)? Why do they change take place?
While employing a compound microscope, you observe a cell which is undergoing mitosis. You see double stranded chromosomes and a partial nuclear membrane. What stage is this cell in?
Would you expect cancer to occur more frequently in types of cells which divide frequently (like skin cells), or in types of cells which divide seldom or not at all (such as nerve cells)? Describe y
If I were to make a cancer drug, at what phase of the cell cycle would the drug be most beneficial? Explain why? How is spending millions of dollars on cancer research to make drugs which target the
If homologous pair separates the normal throughout Meiosis I however do not separate during the anaphase of Meiosis II, what does the end product of that cell division look like? Sketch the end prod
If you think the RNA pill wouldn't work, can you suggest a reasonable hypothesis for the Planaria results? Explain how would you test your hypothesis?
Explain how are binary fission and mitosis dissimilar? Explain how are they similar?
Drugs which inhibit microtubule assembly are administered for some medical conditions. What will take place to the cell as a result? For what kind of conditions would such a drug be provided?
What are some factors which influence the cell cycle? (There are 4 of them that I have to know, but I had liked to know all if possible).
What structures do plant cells possess that animal cells don't? Describe the function of these structures? Where does aerobic respiration occur in the cells of eukaryotic organisms? Illustrate the res
Six centromeres are examined in a prophase cell from an organism. a) At prophase, explain how many pairs of chromosomes does this organism have?
Explain why might programmed cell death (apoptosis) occur via a different mechanism than from the cell death which takes place in necrosis?
Lab mice are immunized with a measles vaccine. Whenever the mice are challenged with the measles virus to test the strength of their immunity, the memory cells don't completely prevent replication o
Most of the cultivated bananas are triploid. Explain how could these be produced from diploid parent banana plants?
There are four kinds of inheritance patterns in pedigrees. What would you expect a pedigree to look similar to for each pattern?
A strain of Neurospora with the genotype HI is crossed with a strain with the genotype hi. Of the progeny, 50 % are HI and 50 % are hi. Describe how this is possible.
An organism has x pairs of chromosomes. This job then derives a common formula to express the number of types of gametic chromosomal combinations possible in this organism.
Predict the outcomes of the given crosses: a) Tall [dominant and homozygous] with dwarf - F1? b) Product of selfed F1.
Garden pea producing round seeds were crossed with such producing wrinkled seeds. The outcome was the production of 5474 round seeds and 1850 wrinkled seeds.
A white albino mouse was crossed with a wild grey colored one. The first generation mice were all grey. In the second generation, there were 198 grey and 72 albino mice.
White fruit color in summer squash is dependent on the dominant allele W and colored fruit on recessive allele w. In the presence of ww and a dominant gene G, the color of the fruit is yellow.
In squash, disc shaped fruit is dependent on the dominant gene D and elongated fruit on recessive allele d. Yellow color is controlled by the dominant gene R and green color by recessive allele r. S
Cross between pure red tomato and yellow tomato generated all red F1 progeny. From the F2 progeny of 400 plants, 90 were yellow. Hypothesize that a single pair of allele is comprised such that Y- =
An animal cell consists of 46 post-mitotic chromosomes in each of its somatic cells. Explain how many chromosomes must be present in the given cells:
