DNA fulfills the function of replicating itself, which is a process in which identical copies of each molecule of the same are made. This replication is essential so that the genetic data can be transferred from one generation to the next, constituting the basis of the inheritance.
<span>The mechanism is given by separating the two chains of the helix from it, to serve as a template in the formation of new chains, which are called messenger RNA. Which are the result of two molecules equal to the first. This replication is called semi conservative, since each molecule resulting from the replication has one chain of the mother molecule and another newly created one.</span>
Proteins are unbranched polymers constructed from 22 standard α-amino acids.
The protein show four levels of structural organisation; the primary structure, secondary structure, tertiary structure and quaternary structure.
The structure of proteins are stabilized by peptide bonds between the amino acid and hydrogen bond between the peptide chainds.
The primary structure of a protein is determined by the sequence of amino acids, but secondary and tertiary structures of protein define their natural or native conformation.
The solubility of protein varies according to the pH, ionic strength, nature of solvent, temperature etc.
Proteins can be classified as simple proteins or conjugated proteins on the basis of their composition.
The proteins can also be classified as fibrous proteins or globular proteins on the basis of their shape.
Proteins play a major part in body structure and function as most of the molecules like antibodies, immunoglobulins, hemoglobin, myoglobin ,most of the enzymes are proteins.
So proteins are also called building blocks of the body.
Answer:
In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.
Answer:
If the fluid is very concentrated, the cell will lose a lot of water, causing the red blood cell to shrink and die. On the opposite side of things, if the body fluids are too dilute (hypotonic), water will diffuse into the red blood cells (because the inside is more concentrated than the body fluid), causing the cells to burst open.
Answer:
Nucleosomes
Explanation:
Nucleosomes
DNA is the heredity matter of the cell .
DNA is enclosed in the Nucleosomes which is present in the cell in the nucleus of the cell .
DNA is condensed together to form chromatin,
and further the chromatin are aligned to form chromosome , that are present in the nucleus of the cell .
Hence , the answer is Nucleosomes .
