Answer:
introduces a premature stop codon into the mRNA
Explanation:
A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.
There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.
Hydrogen, oxygen, and nitrogen atoms.
Answer:
The correct answer will be option-E
Explanation:
The soft cheese like Camembert, blue cheese and feta cheese are prepared from the unpasteurised milk.
Since the milk is not pasteurized therefore there are higher chances that the prepared cheese will have the micro-organism which could be lethal to humans like Listeria. Listeria is a bacteria which gets killed during the pasteurization process.
The pregnant woman should avoid eating the soft cheese as the cheese could contain the harmful bacteria like listeria which once ingested can enter the placenta and can kill the unborn babies or preterm delivery.
Thus, option-E is the correct answer.
