A protein that contains more isoleucine, phenylalanine and leucine than asparagine, lysine and arginine is most likely ________.

Snezhnost [94]

Answer:

The correct answer is: Hydrophobic, Hydrophobic.

Explanation:

Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
The amino acids can be broadly classified into non-polar and polar.
The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.

Escherichia coli has a doubling time of 30 minutes. If a culture has 10 E. coli cells at the beginning of log phase, how many E.

Nat2105 [25]

80 E. coli cells will be in the culture after two hours.

<h3>What is culture?</h3>

The development of the human, plant, or animal cells in a lab, as well as microorganisms like bacteria and yeast. Cell cultures can be used for research, medication testing, and infection diagnosis.

Primary (mortal) cultures and cultures of established (immortal) cell lines are the two main categories of cultures.

One of the most crucial methods in cellular and molecular biology is cell culture because it offers a platform for studying the biology, biochemistry, physiology, metabolism, and other aspects of both healthy and diseased cells.

A culture of 10 E. coli cells.

Incubation time = 2 hours = 120min

Doubling time = 30min (120/30 = 4)

So, 1 cell - 30min = 2 cells - 30min = 4 cells - 30min = 8 cells - 30min

Therefore, 8 ₓ 10 = 80cells of E. coli at the end of 2 hours of incubation time.
