alukav5142 [94]

Answer:

The correct answer is - To dissolve the cell and nuclear membranes and release the DNA.

Explanation:

The major function of the detergent in DNA extraction is to dissolve the cell and cellular membranes. It can increase the membrane permeability by pulling apart lipids and proteins that are components of the nuclear and cellular membrane and lyse the cell, from which we want to extract the DNA.

Detergents cause pores in the cell membranes and once these membranes are completely lysed the DNA is released from the cell. It is similar to detergents removes fat (lipids) from dishes.

Mendel bred an unknown plant displaying a dominant phenotype with an individual showing the recessive phenotype; then, he analyz
kodGreya [7K]

What Mendel did according to the illustration would be called test-crossing.

<h3>Test-crossing</h3>

In genetics, test crossing is a procedure through which the zygosity of an individual can be determined - whether it is homzygous or heterozygous.

Test crossing requires that an organism who displays a dominant trait but whose zygosity is unknown is crossed with another organism of the same species but who displays the recessive version of the same trait.

By so doing and using the knowledge of probability, the resulting offspring from the cross will be used to determine the zygosity level of the parent.

Using the ultrasonication and agitation method of liposome preparation, what concentration of lipid is necessary to prepare lipo
Galina-37 [17]

The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

<h3>What are liposomes?</h3>

Liposomes are vesicles which are made up of a lipid bilayer membrane.

Liposomes are important as delivery vehicles for substances such as drugs.

Ultrasonication is a method of liposomes preparation.

Solution of liposomes is dependent on the size.

The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.

Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
