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.
Answer:
an S strain and mix it with cells of an R strain
First of all, you spelled during wrong, but whatever, It still makes sense and i will still solve it. Your answer to this is: This is a short answer but still alliable. I think, and know at the same time, it is mitochondria.

Answer:
True or false: Typically, once a protein is synthesized in a healthy cell, it will perform its function indefinitely because the cell environment is highly controlled.
=
False
The safety procedural step that must always be performed
when setting up a vacuum filtration apparatus is that first, you should always
wear the proper protective equipment, next is that the vacuum filtration—you should
clamp the flask of which is needed, securely to the ring stand. It must be
secure or it may be in the way of performing the experiment.
