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.

A scientist is conducting an investigation that involves water, silver, carbon dioxide, and oxygen gas. Which group of statement
ivanzaharov [21]

Correct answer choice is:

<h2>D. They are each made of matter. Some are compounds made of one type of element. Some are pure atoms.</h2><h3>Explanation:</h3>

The matter is a substance that has inertia and holds bodily area. According to advanced physics, matter consists of several kinds of particles, each with volume and area.

A pure element indicates a substance whose atoms possess the equivalent atomic number or number of protons.

Silver is extensively utilized as a manufacturing catalyst for the composition of ethylene epoxide via ethylene oxidation and for formaldehyde via methanol oxidation. Oxygen classes on silver are determined to perform a pivotal use in ethylene epoxidation and particular methanol oxidation.

The outcome of the reaction between hydrogen gas and oxygen gas is water vapor (gas).

Water and carbon dioxide are compounds composed of various elements, whereas, silver and oxygen remain pure elements.
