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.
Where does this come from in each of the new cells that are formed after cell division? Yes, DNA also has to divide. The important characteristic of DNA is its ability to make several copies of it. The process of making copies of DNA strand in nucleus of the cell is called replication. The cell divides into two and distributes each copy of DNA into the divided cells. Through replication the DNA transfers the information necessary for creating an exact copy of it in the new cell.
