The answer is a hair root.
Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, d<span>ead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.</span>
1.) It is True that when a cell is put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane.
2) It is False that a when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell.
3) It is True that when a cell is out into a hypotonic solution, there is net movement.
4) It is False that the movement of any solvent across a semi-permeable membrane is called osmosis.
Clostridium botulinum is an anaerobic, spore-forming, bacterium organism that releases a toxin that causes muscle relaxation. The toxin that is released is a neurotoxic protein: Botulinum toxin (BTX) and <span>is produced only in an anaerobic environment. </span>This toxin is used as a a medicine to treat overactive muscle movement.
