Which of the following statements about DNA isolation from E. coli is not correct?

Biology
1 answer:
Ulleksa [173]2 years ago
4 0

Answer:

The correct answer is c. detergent is used to break apart plant cells to extract DNA.

Explanation:

Here we are talking about DNA isolation in E.coli and detergent is used to break apart the bacterial cell membrane by destabilizing the cell membrane. Detergent disintegrates the proteins present in the cell membrane which causes the rupture of membrane releasing the cell extract outside the cell.  

Detergent is not able to break plant cell because it is made up of cellulose and require blending or mashing. Detergent can only be used to disintegrate the cell membrane because only cell membranes contain lipids and proteins.

Hence, the correct answer is c.  detergent is used to break apart plant cells to extract DNA.

____________ is the process by which inhibitory transmitters cause the inside of the neuron to become more negative.
lidiya [134]

Answer:

Hyperpolarization

Explanation:

At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).

It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.

Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ________ ends of glucose polymers.
Alex787 [66]

Sequential cleavage from the non-reducing terminals of glucose molecules is required for both glycogen degradation and polysaccharides hydrolysis.

Why non-reducing end is selected for digestion?

A polysaccharide's non-reducing end is the one where an anomeric carbon participates in the glycosidic connection. The elimination of carbohydrate remnants one at a time out from the non-reducing terminal occurs during glycogenolysis and polysaccharides hydrolysis.

  • For example, several enzymes are involved in glycogenolysis in the liver and muscle.
  • An example of such an enzyme is glycogen phosphorylase, which catalyzes the successive dissociation of the alpha 1->4 glycosidic bond that connects two glucose molecules at a non-reducing terminal of glycogen. The last glucose residue is eliminated as alpha-D-glucose 1-phosphate.

That is why non-reducing end of glucose is chosen for digestion or breakdown of the carbohydrate polymer.
