Question

Which statement about denaturation given below is correct?
Statements:
A ) denaturation of proteins causes loss of secondary and tertiary structures of the proteins.
B) denaturation leads to the conversion of a double strand of DNA into a single strand.
C) denaturation affects primary structure which gets distorted.
a) A,B and C
b) B and C
c) A and C
d) A and B

Answer 1

Hint:We first study the process of denaturation and see what things happen when the process of denaturation occurs. The denaturation is basically the disruption or destroying of the original structure of proteins.

Complete step-by-step answer:As we know that proteins are nothing but the long chains of amino acids.
Further as they are long chains therefore they can be denatured .Now you must be thinking that what is denaturation. So denaturation is the disruption of the protein structures These disruption is of only secondary and tertiary structures . we should know that the protein structures are present in all the three forms that are primary, secondary and tertiary structure. As during denaturation the peptide bonds are unable to break that is why primary structures do not get affected and remain the same. So according to this information we can conclude that the option C is incorrect and option a is correct till now according to the above discussed part.now we will talk about the strands in order to check whether the second statement is correct or not.also it is important to note here that the alpha helix and beta sheets gets disrupted and leads to formation of proteins which are of the random shape. Further talking about the DNA strand so as we discuss the denaturation that means the disruption of DNA strand . so when we heat the protein upto ninety eight degree celsius then as we know that DNA is a double stranded structure so when we heat it up then the protein structure gets denatured and leads to the formation of a single strand.

Note:We should note here that when food is cooked the denaturation happens and that’s why the boiled eggs become hard and cooked meat becomes firm.
