(D). The replacement of a single base, producing a stop codon.
Mutations represent permanent changes in genetic material due to alteration in DNA sequences. A mutation converts a sense codon (codon that codes for a particular amino acid) to a stop codon, is known as nonsense mutations.
It leads to formation of a non-functional and truncated protein as due to stop codon translation halts in middle.
Thus, the correct answer is option (D).
a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.
what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?
a.the enzyme’s hydrogen bonds will break.
b.the activation energy will increase.
c.more product will be formed.
d.the ideal temperature and ph for the enzyme function will decrease.
it is a learned trait
a. the replacement of a single bas...
