Answer:

integrinas y lamininas

Explanation:

Las integrinas son glucoproteínas implicadas en el anclaje de las células epiteliales a la matriz extracelular. Las células epiteliales tienen en su base proteínas integrinas que se unen a otras proteínas tales como vitronectina, fibronectina, colágeno y laminina. De este modo, las integrinas se asocian con lamininas de la lámina basal. Las lamininas son otra clase de glucoproteínas las cuales conforman la lámina basal y contienen sitios de unión para integrinas. A partir de esta asociación las células epiteliales pueden adherirse a la membrana basal y mantener su orientación dentro de un tejido. Estas uniones son fundamentales para que las células epiteliales puedan soportar fuerzas y son críticas durante el desarrollo apropiado (ontogenia) del organismo.

The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.

<h3>What are restriction enzymes?</h3>

They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.

The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

The type of local anesthetic patch that would be indicated is Lipoderm.

<h3>What is Lipoderm?</h3>
  • Transdermal delivery of drugs for pain, nausea, and veterinary usage has been accomplished with Lipoderm.
  • When treating pain, several medications might be combined to focus on the many pain-causing factors.
  • Lipoderm is a particularly efficient medicine delivery system for cats since it penetrates the inner ear skin.
  • A patented liposomal component in Lipoderm, a chic substitute for conventional PLO gels, may improve the permeability of a number of active ingredients.
  • In contrast to PLOs, which have a sticky feel, it is smooth and creamy to the touch.
  • An anhydrous form of Lipoderm, PCCA has been developed for active pharmaceutical ingredients (APIs) that are unstable in water.
