Variations in gene expression that occur without alterations in DNA sequence are called _____ modifications.
A)epigenetic
B)nutrigenomic
C)nutrigenetic
D)biogenetic

Question

Quizplus · Accepted Answer

Epigenetic modifications refer to changes in gene expression that do not involve alterations to the DNA sequence itself. These modifications can be influenced by a variety of factors, including environmental factors, lifestyle choices, and developmental processes. Examples of epigenetic modifications include methylation of DNA and modification of histone proteins. Nutrigenomics and nutrigenetics both refer to the study of how diet and nutritional status affect gene expression, but they do not encompass all types of gene expression modifications. Biogenetic is not a term related to gene expression or modification.
