[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
the number of amino acids determines the tertiary structure of the protein
|
|
|
the interactions of the different R-groups with other R-groups and with their environment determine the tertiary structure of the protein
|
|
|
the R-group of the last amino acid that is added to a growing polypeptide chain determines the next amino acid that is added to the chain
|
|
|
the sequence of the amino acids in the polypeptide chain determines the protein’s primary structure but has no effect on it’s tertiary structure
|
Detailed explanation-1: -Which of the following best describes how amino acids affect the tertiary structure of a protein? The interactions of the different R-groups with other R-groups and with their environment determine the tertiary structure of the protein.
Detailed explanation-2: -Tertiary structure The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as -helices and -strands.
Detailed explanation-3: -The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.
Detailed explanation-4: -Which of the following best describes the tertiary structure of a protein? AThe tertiary structure of a protein is the folded structure (alpha-helix or beta-sheet) formed by additional bonds that are formed in the polypeptide chain.
Detailed explanation-5: -Covalent Bonds-Disulfide Bridges Cysteine is the sole amino acid whose side chain can form covalent bonds, yielding disulfide bridges with other cysteine side chains:–CH2-S-S-CH2–.
