Question

Quizplus · Accepted Answer

Epigenetics is the study of heritable changes in gene expression without change in the DNA sequence. This can include modifications to DNA itself (such as methylation) or to the proteins (histones) around which DNA is wrapped. Molecular biology is a broader field that encompasses the study of genes, their function, and their regulation, among other topics. Genetic engineering involves making deliberate changes to the DNA sequence of an organism. Molecular cloning is a laboratory technique used to amplify DNA sequences.
