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 is the code that directs a cell's actions. In eukaryotes (cells with nuclei, like you have), the DNA is stored in the nucleus. When a gene (a segment of DNA coding for a s â¦ pecific trait) is expressed, a protein is made to fulfill some cell function.
