Indicate whether the following statements are true or false...

Indicate whether the following statements are true or false. If a statement is false, explain why it is false. A. Generally, the total number of nonpolar amino acids has a greater effect on protein structure than the exact order of amino acids in a polypeptide chain. B. The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. C. The chemical properties of amino acid side chains include charged, uncharged polar, and nonpolar. D. The relative distribution of polar and nonpolar amino acids in a folded protein is determined largely by hydrophobic interactions, which favor the clustering of nonpolar side chains in the interior.

00:01 Question 1 discusses about the effect of non -polar and polar amino acids on the protein structure.

00:09 An amino acid is said to be non -polar when it has a reduced affinity towards the water molecular.

00:17 Whereas an amino acid is said to be a polar amino acid when it has an increased affinity towards the water molecule.

00:26 Let's write aa for amino acids.

00:28 So, the polarity of the amino acids is more important than the order of the amino acid sequence in a proton.

00:37 The reason behind this is that the order of amino acids that is seen in a protein sequence can alter a structure to a small extent.

00:47 But this polarity in turn will decide whether the protein needs to be folded or not.

00:53 Because non -polar amino acids cannot be exposed to the outer surface.

00:59 Which has water.

01:01 Hence, this in turn will make the proton undergo a different folding pattern and different folding pattern can alter the function of a particular proton.

01:11 Hence, the function of a particular photon get completely disrupted based on polarity than the based on order of an amino acid sequence.

01:19 Hence, for the first question that is, sorry, question a, this is question a.

01:25 The question a, it is true.

01:28 The correct answer to the question is true.

01:31 And question b discusses about the polypeptide backbone.

01:36 The polypeptide backbone here denotes the chain of amino acids.

01:41 That is, when amino acids are connected to each other, they form the polypeptide backbone...
