Q:

What is therapeutic cloning?

A:

Quick Answer

The National Institutes of Health defines therapeutic cloning as cloning an embryo only for the purpose of producing embryonic stem cells with the same DNA as the donor cell. Therapeutic cloning aims to create stem cells for the express purpose of experiments so that researchers gain a better understanding of disease and work to develop effective treatments for diseases in humans.

Full Answer

While part of the goal of therapeutic cloning involves learning more about molecular causes of diseases, researchers also hope to grow healthy tissues to eventually replace diseased or injured tissues. They also use the cells cloned in the process to test new therapeutic drugs. Still, researchers find some drawbacks to cloned cells because they see many similarities between cancer cells and stem cells. Stem cells have the ability to multiply indefinitely in the same manner as cancer cells. After a few cycles of cell divisions, these stem cells may acquire the same mutations that occur in cancer cells, ultimately defeating the purpose of therapeutic cloning. Yet, this connection between stem cells and cancer cells drives lots of research in therapeutic cloning for researchers who feel it is necessary to understand the value of stem cells in the treatment of human disease.

    What is the purpose of photosynthesis?

    A:

    Photosynthesis is a process that allows plants to harvest energy in sunlight and store it chemically, by producing sugars. Sugars hold energy in their molecular bonds; when the plant breaks down these bonds, energy is released that the organism can then use. Although green plants are the most famous photosynthesizing organisms, some bacteria, algae and protists carry out the process as well.

    What is the purpose of mitosis?

    A:

    The purpose of mitosis is cell reproduction, regeneration and growth. Mitosis is cell division that occurs in the nucleus of a cell. The result of mitosis is the formation of two cells, called daughter cells, that are genetically identical to the original cell.

    What is the purpose of compound eyes?

    A:

    Compound eyes give insects an expanded field of view, according to University of Minnesota (UMN). Compound-eyed insects, such as the dragonfly, can see objects from all angles except for the blind spot their bodies create. Some boast dual-vision systems which allow them to see darkness, light and color. Compound eyes also help insects estimate the distance between their bodies and other objects, states PawNation.

    What is the purpose of the metatarsal bones?

    A:

    Metatarsal bones bear most of the weight in the foot when humans walk. There are five metatarsal bones, numbered one through five. These structures provide the shape of the arch in the foot. The first metatarsal is shorter than the other four, and the remaining metatarsals are the same length.
