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 occur without altering the DNA sequence. These modifications include changes in DNA methylation, histone modifications, and non-coding RNA regulation. Nutrigenomic and nutrigenetic refer to the study of how nutrition affects gene expression and how genetic variations affect nutrient metabolism and response, respectively. Biogenetic is not a term commonly used in genetics or molecular biology.
