A common column material used in size-exclusion chromatography is dextran, a polysaccharide of glucose. Which type of interactio

Yuliya22 [10]

Answer:

Hydrogen bonding

Explanation:

A hydrogen bond is a form of the electrostatic force of attraction which takes place between the hydrogen atom and a more electronegative atom such as nitrogen, fluorine, and oxygen.
Hydrogen bond falls in the category of weak forces.
In size-exclusion chromatography, the type of interaction that takes place between the proteins and dextran is hydrogen bonding.
The hydrogen bonding is possible because dextran, being a polysaccharide of glucose has several hydroxyl groups and thus, they get involved in the hydrogen bonding.

What are the four types of tissues?

ElenaW [278]

The term ''tissue'' refers to a group of similar cells. Being a combination of equal cells, a tissue has the same function in any part of the body.

The four types of tissues are:

. The epithelial tissue

. The connective tissue

. Muscle tissue

. The nervous tissue

. The epithelial tissue serves as a cover, among these are the skin and the lining of several ducts inside the body. It is divided into two general classifications: Simple Epithelium and Stratified Epithelium.

. The connective tissue supports and joins other tissues such as bone, blood and lymphatic as well as adipose tissue and reticular tissue.

. Muscle tissue consists of striated or voluntary muscles that move the skeleton and smooth muscle, such as the one that surrounds the stomach. It is divided into three types: Skeletal Muscle Tissue, Cardiac Muscle Tissue and Smooth Muscle Tissue.

. Nervous tissue is formed by nerve cells or neurons and serves to carry messages to and from various parts of the body. This tissue is present mostly in the brains and spinal cord. It has two types of tissue: The Nerve Cell and the Neuroglia.

Which of the following

Pachacha [2.7K]

Phosphate groups of the nucleotides in the diagram are marked with W.

Option C.

<h3><u>Explanation:</u></h3>

DNA is a macro molecule which is formed of polymerization of deoxyribonucleotides. Four types of deoxyribonucleotides are present which are adenosine, guanosine, thymidine and cytosine triphosphate. These nucleotides are polymerized based on the genetic setup.

The phosphate groups attached with the sugar molecule are actually polymerized with the o glycosidic bond. That's marked with the letter W. These phosphate molecules are attached with the sugar molecules which actually are attached with the nitrogen bases. They in total forms a nucleotide, hence the whole DNA. X in the diagram are nitrogen bases and the Y are the hydrogen bonds between the complementary nitrogen bases
