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 autonomic (involuntary) nervous system controls the rate at which the heartbeats. sympathetic (fight or flight) signals speed up the heart’s rate while parasympathetic (rest and digest) signals slow it down. The part or parts of the heart that forms sympathetic and parasympathetic neurons form synapses is called cardiac plexus.
Cardiac plexus is a plexus of the nerves that are present at the base of the heart and is divided into superficial and deep part. The sympathetic and the parasympathetic nerves form synapses with heart in the form of cardiac plexus.
The sympathetic nerves are responsible for activating flight or fight mode while parasympathetic nerves are responsible for restoring the normal body state.
