(The Double Helix) DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
There is something called the lock and key mechanism; it has a shape that fits the substrate like a lock fits a key only substrates with a particular molecular shape
<h2>d) option is correct </h2>
Explanation:
The stringent response occurs in response to low energy store
For example when there is low level of lactose it means energy level is low so there will be no transcription of genes and hence transportation and catabolism of lactose will be inhibited
When E coli is grown in mixture of both glucose and lactose, at high glucose concentration the growth rate is maximum and lactose catabolism is repressed, this called as catabolite repression and it is due to level of cAMP

Answer:
<h2>The changes that do not affect the function of a protein are called silent mutations.</h2>
Explanation:
As given here as a mutation occurs in an original DNA template that changes the DNA, by transcription this mutation passes into RNA and changes the RNA, but it does not change the protein sequence, it means that this mutation could be silent mutation.
Silent mutation is the mutation which cause the change of a base in that, after the mutation the codon codes for the same amino acid, or the amino acid which do no cause any change in the protein, hence these changes do not affect the function of a protein.
