Genes are segments of DNA located on chromosomes. A gene mutation is defined as an alteration in the sequence of nucleotides in DNA. This change can affect a single nucleotide pair or larger gene segments of a chromosome. DNA consists of a polymer of nucleotides joined together. During protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop the disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.

Since, the options are not given the question is incomplete. The complete question is as follows:

The laboratory analysis conducted on a child with chronic nasal drainage reveals an elevated number of eosinophils on a white blood cell differential. Based on this finding, which is most likely the cause of the nasal drainage?

a. Bacterial infection

b. Viral infection

c. Chronic inflammation

d. Allergies

Answer: d. Allergies

Explanation:

During the allergy the eosinophils are recruited at the site and these are produced in large number by the bone marrow cells. The allergic conditions may developed during the sinus infections where chronic nasal drainage occurs in order to expel out the pathogen from the body. The parasitic diseases and allergic reactions will result in the excess production of the eosinophils.

The given situation is a result of the allergic reaction which brought about large increase in the number of eosinophils.
