Proteins and nucleic acid - answer Important biomolecules that make the
different dynamic processes in living organisms possible


Protein - All biological processes require the presence


Nucleic acid - Biomolecules responsible for storing, transmitting and
expressing hereditary information


Life would not have been possible without these two biomolecules


Nucleic acid - answer Biomolecules responsible for storing, transmitting
and expressing hereditary information


Proteins - answer Have many functions in cells and between cells,
mediating and participating in many processes


Polypeptides- Consist of long chains of amino acids


Amino acids - Monomers or building blocks of proteins

, Usually 100 to 10,000 amino acids in a typical protein molecule


Polypeptides - answer Consist of long chains of amino acids


Amino acids - answer Monomers or building blocks of proteins


Protein structure - Depends on the following four hierarchical
organizations:
- Primary
- Secondary
- Tertiary
- Quaternary - answer Levels of Protein Organization


Primary structure - answer Simply the order of amino acids in a
polypeptide strand.


Amino acid sequence - answer Main determinant of the overall structure of
the protein and determines its ultimate biological function


Secondary structure - answer Local three-dimensional folding of the
polypeptide chain in the protein.


Alpha helix - answer Spiral


Beta sheet - answer Beta strand forming an accordion-like pleated sheet


Tertiary structure - answer Formed when the distant segments of a
primary structure and the relationships of the side chains are bound in a
three-dimensional folding of the entire polypeptide chain.
