Summary Introduction

Introduction:

The subunits of proteins are held together by the help of bonds called amino acids. The bonds within the atoms are also held by hydrogen bonds. The amino acid cysteine has sulfur-containing R group which forms covalent disulfide bonds.

Fill in the following with the specific bond(s): Maintain(s)the helical structure of many proteins____________: ;link(s) polypeptide chains and can cause proteins tobend:_______ and________ ; join(s) the twostrands of the double helix of DNA:_________ ; link(s) amino acids to form the primary structure of proteins:_______.
Protein structure is directly related to function. Which of the following statements is true regarding this concept ? Polypeptide backbone -CH2 – CH, – CH2- CH2- NH3 0-c- CH - CH2 lonic bond Hydrogen ! bond C- NH2 Disulfide linkage CH CH2 HạC CH3 CH3 H3C CH -CH2 Hydrophobic interactions A. The primary structure consists of the DNA sequence. The secondary and tertiary structures are dependent on interactions between the DNA and RNA polymerase. Mutations resulting in changes one or more bases has the potential to destroy the structure, and therefore the function, of the protein. B. The primary structure consists of the amino acid sequence. The secondary and tertiary structures are dependent on interactions between the amino acid side chains. Mutations resulting in changes one or more amino acids has the potential to destroy the structure, and therefore the function, of the protein. C. The primary structure consists of the DNA sequence. The secondary structure consists of the amino acid…
This image shows the tertiary structure of a protein segment. Tertiary structure results from different interactions, or forces, between groups. Move the example of each force to the appropriate description on the protein. Then, identify the major force controlling tertiary structure. (Need help) It says I'm wrong.
