Answer:

Endothelium provides a slick surface lining all hollow cardiovascular organs.

Explanation:

Endothelium is a layer made of cells that lines the interior surface of the entire circulatory system from heart to the capillaries. It forms the interface between the blood in the lumen and the vessel wall.

It is a single celled thin layer of squamous cells. It is involved in fluid filtration, maintaining the the blood vessel tone, homeostasis, hormone trafficking and neutrophil recruitment. It is of mesodermal origin. It is aligned in the direction of fluid flow.

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu
uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

  • Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
  • Forward and reverse primers (to customize the start of the enzyme reaction)
  • DNA polymerase (Enzyme required for replication of desired DNA region.)
  • DNA Template (the DNA to be copied)
  • PCR-grade water
  • Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
