Cranberry Assay Lab Report

The very first step of my experiment is to get all the equipments and materials I need. What I need for this experiment are six kinds of berries I chose, enough yeasts, x-ray machine and materials for comet assay. The first step of my experiment is to give berries to the yeast. I will give berries to yeast by blending the berries using the blender, and then whiz it, so I can add the juice from the berries to the yeast. While I am doing my experiment I will have to decide how much juice I add to yeast. Then after adding the juice I will x-ray the yeast with the x-ray machine, with the help of an adult. After x-raying the yeast I will use the comet assay technique to see if it damages it or no. My final step is to collect the data.

Risk/ Safety

As far as my experiment, on finding if the

The only risky part of my experiment is doing x-rays. X-rays are harmful because exposing to a lot of radiation from x-ray can cause radiation sickness. As I said, x-rays are form of ionizing radiation. When normal light hits an atom, it doesn’t change the atom in any significant way, but when an x-ray hits an atom, it knocks electrons off the atom to create an ion. Ion is an electrically-charged atom. An ion's electrical charge can lead to unnatural chemical reactions inside cells. Among other things, the charge can break DNA chains. A cell with a broken strand of DNA will either die or the DNA will develop a mutation. And if a lot of cells die, the body can develop various diseases. If the DNA mutates, a cell may become cancerous, and this cancer may spread. The mutation in a sperm or an egg cell may lead to birth defects. Because of all these risks, doctors use X-rays
