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.
Most of the DNA in eukaryotes is found in the nucleus, while prokaryotes, lacking a nucleus, have their DNA loose in the cytoplasm. Explanation: In eukaryotes, the genomic DNA, which makes up most of the cells DNA, is contained in the nucleus. There is additional DNA in the cells mitochondria, and still more in the chloroplast if it is a plant cell, but it is a very small amount.
