Polypeptide Chain | Definition Structure - Lesson | Study. com What is a polypeptide chain? The definition of a polypeptide chain is a string of amino acids connected together by peptide bonds The word poly means many, and the word peptide refers to proteins
Primary Structure of Protein | Overview Chemical Composition The primary sequence of a protein is the order of the amino acids in the polypeptide chain The primary structure is coded for in the DNA of organisms and can be read through protein synthesis
Frameshift Mutations | Types, Examples Effects - Study. com The DNA is mutated (bases are inserted or deleted), which causes changes in the RNA sequence and resulting polypeptide Frameshift mutations occur in two types - insertion mutations and deletion
The Role of Ribosomes and Peptide Bonds in Genetic Translation Ribosomes live on the endoplasmic reticulum surrounding the nucleus and are key in the process of polypeptide assembly This is essential for genetic translation because amino acid chains are
Tertiary structure of proteins can be created by: a) Hydrogen bonding . . . Protein Structure: Protein structure is composed of four levels called primary, secondary, tertiary, and quaternary structure Primary structure is the polypeptide chain Secondary structure is the hydrogen bonding of the polypeptide backbone and makes up alpha-helices and beta-sheets Tertiary structure is the interactions of amino acid side groups Quarternary structure is two or more
