A good expression vector for protein expression in coli should have which feature(s)?
kicyunya [14]

A good expression vector for protein expression in coli should have features like an origin of replication,  a selectable marker, a promotor, an operator, and a ribosome binding site.

A Ribosome Binding Site (RBS) is a part or segment of the upstream part of a messenger RNA (mRNA)  molecule which binds the ribosome to position the message correctly for the initiation of translation.

Selectable marker genes are conditionally dominant genes that confer an ability to grow in the presence of applied selective agents that are normally toxic to cells or inhibitory to growth, such as antibiotics and herbicides.

Which of the following statements best describes what happens when a bacterial cell is placed in a solution containing 5 percent
lora16 [44]

Answer:

C) Water will move out of the cell.

Explanation:

In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.

This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.

Because of the great deal of active transport that occurs here, the _________ of all the nephrons collectively account for about
bearhunter [10]

Answer:

Because of the great deal of active transport that occurs here, the <u>proximal convulated tubules</u> of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.

Explanation:

Proximal convulated tubule is responsible for transport of a very large number of substances mentioned below :

  • Sodium bicarbonate
  • Sodium Chloride
  • Glucose
  • Amino acid
  • Organic solutes
  • K ions are absorbed via paracellular pathway.
  • Water is absorbed passively.

Transporters include :

  • Na/K transporter
  • Na/HCO3 transporter
  • Na/glucose
  • Na/Amina acids

As a large number or transporters are present in the PCT , large amouny of ATP is cleaved here, and about 6% of daily resting ATP and caloric consumption occurs.
