Cancer cells are different because they don't enter the G - 0 phase and they are likely to do which of the following Your answer
Allisa [31]

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

Why was ice used during the extracting DNA
AfilCa [17]

Answer: The Cold Water  temperature helps increase the attachment of the DNA Explanation:

Using ice-cold ethanol and ice-cold water increases the yield of DNA. Low temperatures protect the DNA by slowing down the activity of enzymes that could break it apart. ... DNases in the cytoplasm would destroy the DNA of viruses entering the cell. Cold ethanol helps the DNA to precipitate more quickly

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color e
RSB [31]

Answer:

75% red, 25% other color (brown?)

Explanation:

A cross between two heterozygous red eye flies (Rr x Rr)

                     R                     r

R                  <em>RR                   Rr</em>

r                   <em>R</em>r                   <em> rr</em>

<em />

The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.

Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)
