Which of the following cell organelle is stored the information of synthesize Proteins?

The nucleus is the cell organelle that stores the information for synthesizing proteins. It contains the cell's DNA, which has the genetic instructions for protein synthesis. The mitochondria, chloroplast, and cell membrane do not store genetic information.
Find out the Miss matched pairs:

The statement 'Protein – important compounds of nucleus' is incorrect. Proteins are not the main constituents of the nucleus; nucleic acids (DNA and RNA) are. Proteins have various functions throughout the cell, but they are not specifically the important compounds of the nucleus.
Which of the following are linked together to form Proteins ?

Proteins are made up of amino acids. These amino acids are linked together by peptide bonds to form long chains, which then fold into specific three-dimensional shapes to form proteins. Amino acids are the building blocks of proteins, making option 'o4: Amino acids' the correct answer.
Which one of the following is incorrect for Protein:

Proteins are primarily composed of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). Some proteins may also contain sulfur (S) but not phosphorus (P) as a major component. Therefore, option 'o3: They possess C, H, O, N and P in their constitution' is incorrect.

which of the following secondary metaboliteis used as a lecitin?

concanavalin A falls under the category of lecitin

Which one is the most abundant protein in the animal world?

Collagen is the most abundant protein in the animal world. It is a structural protein found in connective tissues such as skin, tendons, and bones, providing strength and elasticity. Therefore, option 'o1: Collagen' is the correct answer.
Polypeptide chain of amino acid is:

A polypeptide chain of amino acids forms a protein. Proteins are composed of long chains of amino acids linked together by peptide bonds. Each amino acid in the chain is referred to as a residue, and the sequence of these residues determines the protein's structure and function.
The structure of protein can be destroyed by which rays

Ultra violet rays can destroy the structure of proteins. UV radiation can cause the breaking of peptide bonds and the formation of cross-links between protein chains, leading to denaturation and loss of function.
Amino acid is an amphoteric compound because:

Amino acids are amphoteric compounds because they contain both an amino group (-NH2) and a carboxyl group (-COOH). The amino group can act as a base (accepting a proton), and the carboxyl group can act as an acid (donating a proton), making amino acids capable of reacting both as acids and bases.
The unique property of each amino acid is determined by its particular:

Each amino acid has a unique side chain, known as the R group, that determines its distinct properties. The –COOH group (carboxyl group) and –NH2 group (amino group) are common to all amino acids, while the peptide bond links amino acids together. Therefore, the specific characteristics of each amino acid are determined by its R group.
Which of the following is the most widely classification method of amino acid:

No explanation available.
Find out the one group of amino acids which are related with each other:

Serine and Tyrosine are both amino acids with polar side chains that contain hydroxyl groups (-OH). This similarity in their side chain structures relates them to each other. Valine and Histidine, Glutamate and Proline, Lysine and Leucine have different types of side chains and are not as closely related.
Aspartic acid and lysine are linkage each other with which bond:

Aspartic acid and lysine are amino acids, and the bond that links amino acids together is called a peptide bond. Peptide bonds are formed through a dehydration synthesis reaction between the carboxyl group of one amino acid and the amino group of another.
Dipeptide means:

A dipeptide is a molecule consisting of two amino acids linked by a single peptide bond. These amino acids can be either similar or dissimilar. Thus, the correct definition of a dipeptide is two similar or dissimilar amino acids attached by a peptide bond.
Which macromolecule is the most diverse in cell and controlling biochemical Properties?

Polypeptides, which are proteins, are the most diverse macromolecules in cells and they play a crucial role in controlling biochemical properties. Proteins are involved in a wide variety of functions including catalysis of biochemical reactions (enzymes), structural roles, signaling, and transport.
