First-degree burns affect the outer layer of skin, which is called the epidermis. They are moist, red in color and cause pain, redness and swelling. First-degree burns are partial-thickness burns because of their depth. They will heal spontaneously.
Nucleus. DNA can be found inside the nucleus of every cell, apart from red blood cells. It's tightly wound and spread throughout the 46 chromosomes. One set of 23 chromosomes is inherited from each parent. Inside the chromosomes the DNA exists as genes.
DNA contains the instructions for making you. How you look, what blood type you have, even your tendency to get some diseases. It is found inside the nucleus in just about every single cell of your body. In this lab, you'll break away the membrane around the cell and its nucleus so that you can see your very own DNA.
