Answer:

How does PCR work? To amplify a segment of DNA using PCR, the sample is first heated so the DNA denatures, or separates into two pieces of single-stranded DNA. Next, an enzyme called "Taq polymerase" synthesizes - builds - two new strands of DNA, using the original strands as templates.

An epithelial tissue has multiple layers, flat and irregular cell shape, dead outer layers of cells, and keratin present in some
Rudik [331]

This is stratified keratinized squamous epithelium.

<h3>What are the characteristics of stratified keratinized squamous epithelium?</h3>
  • A kind of stratified squamous epithelium known as keratinized stratified squamous epithelium has cells that have multiple layers of thick keratin in the apical portion of the cells.
  • Skin and underlying tissues can benefit from the stiff, fibrous intracellular protein keratin's ability to protect them from heat, bacteria, and chemicals.
  • In the process of keratinization, the cells build up keratin as they ascend, transforming into thin, metabolically inert pockets of keratin devoid of nuclei.
  • As cells distance themselves from the nutritive blood supply and the organelles eventually perish, the relative amount of keratin in the cells rises.
  • The cells on the top layer lose all function as a result of keratinization and are now primarily involved in protecting against mechanical stress and dehydration.
