notsponge [240]

The technology that was used to produce the results illustrated in the image is gel electrophoresis and it is used for separating deoxyribonucleic acid (DNA) fragments.

Gel electrophoresis can be defined as a technology that is used in the laboratory for the separation of mixtures of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or other macromolecules such as proteins based on molecular size and charge.

In gel electrophoresis, an electric current is applied to the deoxyribonucleic acid (DNA) samples so as to create fragments that can be used to compare the various samples of deoxyribonucleic acid (DNA).

The steps involved in gel electrophoresis include the following:

  • Extraction of deoxyribonucleic acid (DNA).
  • DNA isolation and amplification.
  • Addition of deoxyribonucleic acid (DNA) to the gel wells.
  • Application of an electric current to the gel.
  • The separation of DNA bands based on molecular size and charge.
  • Deoxyribonucleic acid (DNA) bands are stained.

Choose the correct order of steps for the synthesis of Vitamin D.
n200080 [17]

Answer:

The correct answer will be option-

1. UV light strikes the skin and converts a steroid molecule into an inactive form of vitamin D.

2. Inactive vitamin D is transported to the liver where it is modified.

3. Vitamin D is activated under the influence of PTH.

4. Inactive, chemically altered vitamin D is transported to the kidneys.

Explanation:

Vitamin D is a fat-soluble metabolite which helps maintain the health of the bone by maintaining the calcium homeostasis.

The vitamin D is synthesized mainly in the liver and kidney from the biologically inactive precursor of vitamin D called ergocalciferol and Cholecalciferol.

The inactive vitamin is synthesized in the skin when the skin is exposed to UV rays.  The UV rays convert the 7-dehydrocholesterol, a steroid molecule to Vitamin D3, This inactive vitamin is then transported to the liver where it is converted to 25-hydroxyvitamin D.

This vitamin D form is further metabolized in the kidney controlled and regulated by the Parathyroid glands.
