Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate.
What does DNA extracted from a strawberry look like?
Observe the line between the strawberry mixture and the alcohol. You will notice a white thread-like cloud appearing at this line. This is strawberry DNA. The DNA will clump together and float to the top of the alcohol layer.
What is unique about strawberry DNA?
Strawberries yield more DNA than any other fruit because they have eight copies of each type of chromosome. The long, thick fibers of DNA store the information for the functioning of the chemistry of life. DNA is present in every cell of plants and animals.
We intention extract DNA from fruit to investigate how it examines and feels. This procedure is identical to what scientists have to do before they can use the statement contained in this DNA. This announcement can be used to enhance crops so that they are more resistant to infection, insect invasion, or differences in climate.

The dependent variable alters
These are known as Hormones. Hormones are chemical messengers that are released in one tissue normally endocrine glands for example, adrenal glands, pituitary glands, and transported in the blood stream to alter the activities of specific cells in other tissues. Hormones serves as messengers, controlling and coordinating activities or processes such as growth, metabolism and fertility in the body.
Emperor penguins need lungs to breathe. In penguin lungs, air never stops. ... Once the air goes farther into the trachea it splits into two different directions into both lungs. To get the oxygen into the blood cells, it must come "within small distance of the penguin blood cells".
