<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>
Answer:
The correct answer is option - C. low power objective.
Explanation:
In microscopes, low power objectives have a wide field of view and use to study the many smaller specimens or large specimens. 10X is the power of the low objective.
To study the depth of the field the lower objective rotated and aligned on the place over the specimen. When you move to high power objective the field of view gets close in and only can study the smaller specimen or small section of a large specimen.
Thus, the correct answer is option - C. low power objectives.
it is DNA's Code. hope i helps
In meiosis one, homologous chromosomes only separate resulting in two cells. In meiosis II, the cells divide further, separating sister chromatids and resulting in four cells. So the cells are just even smaller with less chromosomes in each one.
