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.
In eukaryotic cells, such as plant and animal cells, it is the  nucleus that contains the majority of DNA and is sometimes called  the brain of the cell.    The DNA câ¦ontained within the nucleus contains the 'blueprints' or  instructions for the functional products (i.e. proteins) of the  cell.
