A mutation in _____ results in a change in _____ that sometimes produces a(n) _____ with altered structure and function.
xenn [34]

Answer:

A mutation in <u>DNA </u>results in a change in <u>RNA </u>that sometimes produces a <u>protein </u>with altered structure and function.

Explanation:

DNA is the hereditary material which causes gene expression in our body by producing protein. The type of protein which is produced by DNA totally depends upon the sequence of nucleotides in the DNA. But, DNA molecule does not produce protein directly. Initially it produces RNA (mRNA, tRNA, rRNA) by the process of transcription, the nucleotides in the RNA are complimentary to those in DNA. In short, the message regarding the structure and composition of the type protein to be produced by DNA is first decoded from DNA in the form of RNA. These RNA molecules then synthesize the protein as per the instructions from DNA by the process of translation.

But, in case a mutation occurs in the DNA which causes a change in it's nucleotide/nucleotides, the protein which will be produced will be different in the structure and function than the protein which was supposed to be synthesized. It happens because, a triplet of nucletiodes in the DNA and hence RNA specifies a particular type of amino acid and several amino acids are joined in a long chain to form polypeptide which ultimately forms protein. But, if any nucleotide in the triplet is changed due to mutation it may change the amino acid and if amino acid will change the protein will also get altered.

Acetylcholinesterase (AChE) is a protein that catalyzes the conversion of acetylcholine to acetate and choline. When the concent
miv72 [106K]

The correct statement is that the concentration of acetylcholine will be inhibited by enzymes and can cause several diseases as follows:

  • Alzheimer's disease-related to damage to brain cells,
  • memory loss,
  • and thinking ability.

How to reduce the symptoms of these diseases is to use drugs that contain cholinesterase inhibitors.

<h2>Further Explanation </h2>

Acetylcholine is a neurotransmitter that plays an important role in the functioning of the autonomic nervous system. Acetylcholine is one of the most commonly recognized neurotransmitters or nerve stimulating chemicals. These neurotransmitter compounds can be found in the nervous system.

There are several side effects of the acetylcholine drug, which are as follows:

  • Can cause a lot of sweat
  • Excessive salivation
  • Stomach ache
  • Headache
  • Blood vessel dilation
  • Nausea and vomiting
  • Diarrhea is a sign of an increase in parasympathetic tone.
