Answer:

<em>Clostridium perfringens</em>

Explanation:

<em>Clostridium perfringens</em> is a bacterium characterized by being a large, gram-positive, boxcar-shaped bacillus.

It is part of the facultative aerobic bacteria group (they can survive both in the presence or absence of oxygen) and is also a spore-forming bacterium (spores are small structures capable of generating new bacteria).

<em>Clostridium perfringens</em> can cause food poisoning, which results from the ingestion of contaminated food (usually meat and animal products) by the bacteria.

Once in the small intestine, the bacteria releases the toxin that usually causes diarrhea.

At which ocean-floor feature do plates move together?
frozen [14]

Answer:

divergent plate boundaries

Explanation:

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

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).
