Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.
Answer:
prokaryotic: Small cells in the domains Bacteria and Archaea that do not contain a membrane-bound nucleus or other membrane-bound organelles
All carbohydrates are made up of carbon, oxygen, and hydrogen.
The chemical formula for Glucose is
.
The chemical formula for Fructose is the same as that of Glucose. The difference between the two is how they are structured.
The chemical formula for Sucrose is
.
As you can see in the chemical formulas of Glucose, Fructose, and Sucrose, they are all made up of the elements carbon, hydrogen, and oxygen.
The lower respiratory tract is sometimes referred to as the tracheobronchial tree, this describes the branching structure of airways supplying air to the lungs, this includes the trachea, bronchi and bronchioles.
True
Explanation:
Aqueducts are constructed channels for transporting water from one point to another.
- They were first constructed by the Roman to move water from hollow valleys and narrow areas.
- Today, aqueducts include canals, ditches, gutters, channels that are used to carry water.
- Aqueducts aids the movement of water from one place to another.
- Development of aqueducts by the Romans was seen as a great advantage in that civilization.
