In what circumstances might it be important to use gel electrophoresis to separate and identify plasmids and short linear pieces
nadya68 [22]
I believe using gel electrophoresis to separate and identify plasmids and short linear pieces of DNA would be important if one is making a recombinant plasmid and has to verify that he/she has been successful. Gel electrophoresis is a technique that is used to separate mixtures of DNA, RNA, or proteins according to molecular size. The molecules being separated are pushed by an electrical field through a gel that contains small pores.

Glucose is a large molecule that cannot penetrate the phospholipid bilayer of cells. Instead, glucose enters most cells through
bagirrra123 [75]


The term is Facilitated diffusion.

Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.

The energy is provided by the concentration gradient, which means that molecules are transported from higher  to lower concentrations, into or out of the cell.

The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.

Red blood cells use facilitated diffusion to absorb glucose.
