A nurse researcher involved in epigenomics is studying:
A) the role of specific genes.
B) the function of groups of genes in mediating physiologic function.
C) genetic variations and modifications that influence a particular cell.
D) the origin of the structural and functional events leading to disease.
C) genetic variations and modifications that influence a particular cell.
Explanation: A) Through genetics, the role of specific genes is studied. This study involves examining how genetic variations are passed through familial inheritance.
B) Genomics refers to the study of the function of groups of genes in terms of mediating physiologic function. Genomics studies how an inherited genetic trait, such as sickle cell trait, influences the likelihood that an individual will develop sickle cell disease.
C) The study of all genetic variations or modifications that have influenced a particular cell is referred to as epigenomics. The focus is on the broader picture in terms of studying a complete set of modifications to cellular DNA.
D) The pathogenesis of a disease refers to origin of, or the underlying mechanisms responsible for, the clinical manifestations of that disease. Pathogenesis is the origin of the sequence of events to structural and/or functional alterations in cells, tissues, or organs resulting in disease.
