With proper care and physical therapy, it is possible for the patient to live with minimum or no assistance. As a nurse, give patient ample time for activities and ample time for rest.

Which of these would most likely cause a mutation?
ycow [4]

The right answer is B.

Insertion is a genetic mutation characterized by the entrenchment of genetic material in a chromosome. The insertion size varies between a base pair and an entire sector of a chromosome moved to another. In the latter case, part of the genetic data of the first chromosome is erased. This can happen during an uneven jumping.

The embedding of nucleic bases in a gene makes it longer and shifts the reading of its data, which can modify its functioning in a harmful way, especially if the insertion occurs on the exon (fragments of an RNA primary presence in cytoplasmic RNA after splicing).
