How does cancer affect the cell cycle? What is done differently in the cell cycle?

valentinak56 [21]

Cancer cells affect the cell cycle by not following the checkpoints and dividing abnormally and not getting destroyed by the process of apoptosis leading to the formation of tumours.

In the cell cycle during the mitotic phase the cell divides resulting in two daughter cells and segregation of DNA occurs in this. In cell cycle, there are checkpoints of signalling pathways which determine when the cell has to grow and divide. The healthy cells follow the cell cycle.

Explanation:

Cancer cells become immortal and result in faulty proteins which are not required by the system. The cancer cells grow uncontrollably and are abnormally shaped.

The cell cycle has check points at S phase and G2 phase before it enters the Mitotic phase of division. Normal cells follow the checkpoints.

What evidence did Kendal find that supported his law of independent assortment

Katyanochek1 [597]

The results of the di-hybrid cross of pea plants with round and yellow seeds was the evidence that Mendel fond that supported his law of independent assortment.

Explanation:

Law of independent assortment states that the alleles of two different genes are inherited independent of each other. The law of independent assortment was formulated by Gregor Mendel . Cross of a pea plant with yellow and round seeds with a pea plant having green and wrinkled seeds gave evidence of the law of independent assortment.

When it comes to seed color yellow color is dominant to green. When it comes to seed shape round seed is dominant to wrinkled seed. Let the letter R represent round seed and R represent wrinkled seed. The letter Y represent yellow seed and letter y represent green seed.

The genotype of pea plant with round and yellow seed is RRYY and the genotype of round and wrinkled is rryy. The cross between round yellow and wrinkled green can be represented as follows

$RRYY \times rryy$

Gametes RY ry

F1 generation RrYy RrYy RrYy RrYy

All the plants of the F1 generation have round and yellow seeds.

The F1 generation plants are then bred together

RRYY RrYY RRYy RrYy RrYY rrYY RrYy rrYy RRYy RrYy RRyy Rryy RYy rrYy Rryy rryy r

Are the progenies with phenotypes like round yellow, round green, wrinkled yellow and wrinkled green.

The combination of the characters of roundness and color is observed in the F2 generation proves that the characters of round and yellow as well as wrinkled and green doesn’t appear strictly in combination. This means that they are independently assorted which proves the law of independent assortment.

Which causative organism colonization signifies purulent exudates of greenish-blue pus with a fruity odor?

Damm [24]

The correct answer is: Colonization with Pseudomonas.

Pseudomonas aeruginosa is a Gram-negative, rod-shaped bacterium. It is very widespread because of its advanced antibiotic resistance mechanisms. P. aeruginosa can cause a lot of diseases and it is associate with serious illnesses. It typically infects the airway, urinary tract, burns, and wounds. People with burns or wounds are a high-risk group for skin and soft tissue infections.

What is another term for conventional, or western, medical practices and systems of health care?

melamori03 [73]

Another term for conventional, or western, medical practices and systems of health care is allopathic medicine.
The term “allopathy” was coined in 1842 by C.F.S. Hahnemann to designate the usual practice of medicine (allopathy) as opposed to homeopathy.
 The allopathic medicine treats disease by the use of remedies which produce effects different from those produced by the disease under treatment.
