Part A: For each of the following, please choose the appropriate function of the substance.
Group of answer choices

Liquid Detergent in the Extraction Buffer

Salt in the Extraction Buffer

Alcohol in the Extraction Buffer

Wheat germ

DNases

A) precipitates the DNA
B) source of DNA
C) negates the negative charges in DNA
D) dissolves the plasma membrane and binds proteins and carbs
E) enzymes that cut DNA

Liquid Detergent in the Extraction Buffer- dissolves the plasma membrane and binds proteins and carbs

Salt in the Extraction Buffer -negates the negative charges in DNA

Alcohol in the Extraction Buffer -  precipitates the DNA

wheat germ-source of DNA

DNases - enzymes that cut DNA

Explanation:

DNA is isolated by the purification of the sample in molecular biology.

The role of buffers is to isolate buffer in the optimum pH without degrading the DNA. Major steps involved in DNA extraction are: lysis, precipitation and purification.

Liquid detergent DNA: The fats, carbohydrate and proteins  that make up the cell membrane or membrane around nucleus are broken and DNA gets release.

Salt in the Extraction Buffer: When ionic bond between cation of the salt as Na+ bonds with PO3^2 of sugar backbone of DNA it gets precipitated.

Alcohol in the Extraction Buffer : It aggregates the DNA in the form of pellet and precipitate it.  It basically cleans the DNA of all unwanted impurities. This is purification step.

Wheat germ: To extract DNA from wheat germ, the cellulose cell wall is destroyed first. It is a source of DNA in isolation process.

DNases: Also called deoxyribonuclease enzyme responsible for catalyzing the hydrolytic cleavage of phosphodiester bonds of DNA.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
