Biology
1 answer:
elixir [45]3 years ago

Answer:

They destroy the DNA or RNA

Explanation:

Cancer drugs work by damaging the RNA or DNA. The faster the cancer cells divide, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce apoptosis. Radiation therapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. The radiations also induce apoptosis. Cancer cells whose DNA is damaged beyond repair stops dividing and die. The damaged cells die, they are broken down and removed by the body.

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?
Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.

the fertilization of ovules from plant Q by pollen from plant R results in the productions of seeds. What percent of the genes i
Helga [31]

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.
