You are observing different tissue samples and classifying the cells into their respective stage in the cell cycle. What can you
conclude about Sample B based on these observations? A) Sample B Is is most likely cancerous because most of the cells are in interphase. B) Sample B is most likely cancer tissue because most cells are in some stage of mitosis. C) Sample B is most likely a normal tissue sample because most of the cells are in interphase. D) Sample B is most likely a normal tissue sample because most cells are in some stage of mitosis.
D) Samples A & C indicate cancer due to the large proportion of cells in some stage of mitosis compared to the cells in interphase.
Sample: Number of Cells in Interphase Number of Cells in Prophase Number of Cells in Metaphase Number of Cells in Anaphase Number of Cells in Telophase
We have been given that different tissue samples are in their respective stage of cell cycle.
Ans is option B because cancerous cells tend to divide indefinitely regardless of the presence or absence of growth factors. In cancerous cells G0 check points fail and the cells are always in some stage of mitosis i.e. cell is supposed to be in any of the following stages of mitosis :
frequency of the dominant allele in the population ... 2pq = frequency of heterozygous individuals. A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb.
It makes a person with HIV more able to pass it along. HSV could act as a co-factor to HIV which makes it easier It increases the viral load of HIV and also, HIV would be present in herpes blisters. Genital shedding seen on HIV patients may be increased if they also have herpes.
