In gel electrophoresis why does the dna move toward the bottom of the wall of gel

1 answer:

4 0

The answer is an electric current.
An electric current is running through the gel in the electrophoresis with positive pole on the bottom.Since DNA is negatively charged, it migrates toward the positive pole of the gel, respectively, it migrates toward the bottom of the gel.

The movement of fluids between cellular compartments ________. the movement of fluids between cellular compartments ________. is

zlopas [31]

The movement of fluids between cellular compartments is regulated by osmotic and hydrostatic forces.


Hydrostatic pressure is the force exerted by a fluid against a wall which causes movement of fluid between compartments. This pressure is important for exchanging plasma and nutrients between capillaries and surrounding tissues and also in the nephrons (kidneys) where ensures proper filtering of the blood to form urine. Fluid also moves between compartments along an osmotic gradient (the difference in concentration of solutes on one side of the cell membrane to that on the other side). Water constantly moves into and out of fluid compartments via osmotic gradient.

Answer:

The correct answer will be- Chimera

Explanation:

A chimera is an organism which is composed of cells with different genotypes.

The genetic chimera is produced during the formation of the transgenic organisms mainly animals when every cell of the growing embryo does not receive the introduced genes. This results in the formation of two or more zygotes which when merged form genetic chimera.

Thus, a chimera is the correct answer.

siniylev [52]

Answer:

Spinous process

Explanation:

The rhomboideus minor muscle originates on the spinous processes of vertebrae T2-T5

The rhomboideus minor muscle forms part of the superficial group of back muscles. The muscles in the superficial group are immediately deep to the skin and superficial fascia. They attach the superior part of the appendicular skeleton (clavicle, scapula, and humerus) to the axial skeleton (skull, ribs, and vertebral column).

These muscles are sometimes referred to as the appendicular group, since they are primarily involved with movements of part of the appendicular skeleton.

The rhomboideus minor is located deep to the trapezius in the superior part of the back. It inserts on the medial border of the scapula, is innervated by the dorsal scapular nerve its function is to adduct and elevate the scapula.
