Physician recommends radiation therapy because radiation therapy helps in preventing cellular growth. It uses high-energy radiation to shrink tumor or kill cancer cells. It may be used to cure or to control malignancy when the tumor can no longer be removed or when lymph node involvement is present; also, it can be used prophylactically to prevent spread. Radiation therapy kills cancer cells by damaging their DNA which is the molecules inside cells that carry genetic information and pass it from generation to generation. Radiation therapy can either damage DNA directly or create charged particles within the cells that can in turn damage the DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die and when these cells die, they are eliminated by the body through natural process.
28 find that the cell spends in prophase (number of cells in prophase divided by the total # of cells (36) multiplied by 100)
No, it’s not accurate. The law of conservation of energy states that energy can’t be created or destroyed. Plants transform light energy from the Sun into chemical energy through the process of photosynthesis.
<u>Answer</u>:
The nucleus is primarily stores most of the cell's DNA.
<u>Explanation</u>:
It is made up of two chains which coils around each other, together they form a helical structure tat further carries the genetic information, which will help in the development, functioning and also the growth and reproduction in all known organism and in viruses. The nucleus is stored in it and the nucleus has the genetic material. They are composed of the nucleotides, in which each nucleotide has four nitrogen. These nucleotides are together joined with covalent bond to each other. Together they have the biological information.
