Well, the cell would be out of energy! The mitochondria plays a very important role in cell functions. With out it, it cannot do whatever job that needs to be acquired.
D. It occurs before an organism can reproduce. Meiosis is the replication of sex cells required for sexual reproduction to occur.
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.
