Hi, in the question, amounts of amino acids in two samples of protein is given and the amounts of amino acids are same in both the samples.
00:20
So we need to select an option which says why or why not both the samples is of the same protein.
00:35
So the arrangement of amino acids in a linear fashion is referred to as the primary structure of a protein.
00:49
So it is given that both samples have the same amount of amino acids, which means they have the same amino acid composition.
01:06
But that doesn't mean that they are of the same protein because the order in which the amino acids are arranged in a linear sequence may vary between the two proteins which can change the folding of the proteins leading to change in the tertiary structure or the three -dimensional structure of the proteus.
01:33
So the protein which varies in the three -dimensional structure will be a different protein altogether.
01:42
So the order of arrangement of amino acids is very important for the tertiary structure or holding of proteins.
01:52
So option a which says no, only the nucleotide sequence can tell you if the protein are the same is the wrong option because because of the degeneracy of the codons, a single amino acid can be coded by many different codons.
02:19
So you cannot rely on the nucleotide sequence...
