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>
In a supermarket it is likely that the store will be divided into many categories to ensure the customer is able to find what they are looking for promptly. for example, at Walmart, you may find a clothing section, a toy section, a produce section, toiletries section, makeup section and bakery section among many others. this style of organization allows for customers to know exactly where they must go to find what they are looking for - if they would like to purchase an apple they would go to produce etc.
