How are drugs used as a treatment?

Chemotherapy is the drug used involving cancer. The drugs spread through the body, killing cancer cells or slowing their growth.

How is surgery used as a treatment?

Doctor will enter the body and remove the tumor form the body if possible

What is the rule for the nitrogen bases?

Guanine always pairs with Cytosine and Thymine always pairs with Adenine

How does cancer spread?

If one cells develops in an abnormality in their DNA, then the other cells will gain it when the divide. Over time this forms a mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably. This is called a tumor. It will normally spread when cancerous cells break of from the tumor and travel into the bloodstream

Who discovered the structure of DNA

James Watson and Francis Crick

How can you prevent cancer?

One of the main causes of cancer is smoking. The chemicals are not good for your body and may result in cancer. Another thing is to keep a healthy diet. A diet high in fat, fried foods, and unhealthy ways may cause cancer. A diet that includes a lot of fruits and vegetables can lower the risk for some types of cancer.

What are three ways that doctors can treat cancer

Surgery Radiation Drugs

What are the rungs of DNA made of

The rungs of DNA are made up of a combination of nitrogen bases. There names are Thymine Adenine Guanine Cytosine

How is radiation used as a treatment?

When cancer spreads or if the tumor cannot be removed doctors use radiation or beams of high energy waves that attacked fast growing-cancer cells.

How does cancer begin?

When something damages a portion of the DNA, this change is called a mutation. Cancer begins when mutations disrupt the normal cell cycle, causing cells to divide in an uncontrolled way

What is Cancer

a disease in which cells grow and divide uncontrollably, damaging the parts of the body around them

What is a double helix

a shape that twits like the treads of a screw. Since there is two ladders of DNA, one side would be on helix along with the other would be a double helix

What are the two sides of DNA made up of

a sugar called deoxyribose, alternating with molecules known as phospahtes

DNA Replication

the process that ensures that each daughter cell will have all of the genetic information it needs to carry out its activities

Describe the process of the replication

the two sides of the winding molecule separate, causing the nitrogen bases to split away from one another. This means that the strand that separates will have the opposite nitrogen bases to be paired with, which cause the two strands to be identical. Once the free nitrogen bases have paired up with the original sides, the process will begin again
