Although it's rare, with the odds of getting struck in your lifetime being roughly 1 in 12,000, every now and then a human will provide an attractive target for lightning bolts to unleash their power. And of the roughly 500 people who are struck by lightning each year, about 90 percent survive.
Answer:
Embryo cell or totipotent cell
Explanation:
All organisms during their embryonic stage also known as totipotent cells are composed of cells that are identical in structure and function. These cells can differentiate at a later stage and have the potential to become any cell i.e heart cell, eye cell etc. Embryo is thus just a mass of unspecialized cell which undergo differentiation to then convert into pluripotent and form tissues and hence the organ.
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.
