Name three methods of disrupting cells before fractionation

Biology
1 answer:
sladkih [1.3K]1 year ago
4 0

Extraction, homogenization, and centrifugation are the three processes in cell fractionation.

Cell fractionation is a method for dividing cellular components while yet maintaining each component's unique functionality. This technique was initially applied to show where distinct biochemical activities are located within cells. Subcellular fractionation is also used to help with illness detection and to offer an enhanced source of protein for further purification. To prevent osmotic damage, tissue is routinely homogenized in an isotonic buffer solution. Grinding, mincing, chopping, pressure changes, osmotic shock, freeze-thawing, and ultrasonic waves are a few of the mechanisms for homogenization. After that, the samples are maintained cool to avoid enzymatic deterioration. It is the development of a uniform mass of cells (cell homogenate or cell suspension).

If a pea plant has a recessive allele for green peas it will produce
PilotLPTM [1.2K]

Answer:

Green peas if it does not have a dominant allele for yellow peas.

Explanation:

In pea plants, yellow is the dominant allele color of peas and green is the recessive allele color of the pea. So the genotype that makes yellow color pea is YY or Yy and the genotype that is responsible for producing green color pea is only YY.

This shows that homozygous dominant or heterozygous dominant condition gives rise to yellow color pea and only homozygous recessive condition would give rise to green color pea plants.

Therefore if a pea plant has the recessive allele for green peas it will produce green peas if it does not have a dominant allele for yellow peas.

Which is a component of a phospholipid?
krek1111 [17]
Phospholipids are made up of fatty acids, glycerol, and phosphate.

If you're referring to the structure of a phospholipid, they are composed of a water-loving (hydrophilic) head and a water-fearing (hydrophobic) tail. The tail is made up of long chains of hydrogen and carbon molecules as well.
