Which statement best explains the level of organization of a protein that explains the primary squence of its amino acids? tertiary structure secondary structure primary structure quaternary structure

Answer

           The correct option is primary structure.

Explantion

          A protein is composed of polypeptide chain which are organized into different structure as explain below:

Primary structure

           The primary structure of protein is composed of a single polypeptide chain in which amino acids are arranged in linear form. Only covalent bond (peptide bond) hold the structure.

Example

              Insulin hormone

Secondary structure

            In secondary structure a single polypeptide chain is arranged in beta pleated sheet or in helical form. hydrogen bond and covalent bond responsible for providing stability to structure.

Example

            Myoglobin

Tertiary structure

           In tertiary structure a single polypeptide chain is arranged in three dimension. covalent bond, hydrogen bond and disulfide linkage help in maintaning this structure.

Example

            Secretory proteins.

Quaternary structure

            It is composed of more than one polypeptide chain and arranged in three dimension forming a globular structure. covalent bond, hydrogen bond, disulfide linkage, hydrophobic and hydrophilic interaction help in maintaining this structure.

Example

            Haemoglobin.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
