change the DNA sequence

does not change the “on” and “off’ systems in the GEN What is true about epigenetics is ____
|
Detailed explanation-1: -Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence.
Detailed explanation-2: -Epigenetic marks can be affected by exposure to metals, air pollution, benzene, organic pollutants, and electromagnetic radiation [98]. Chemical and xenobiotic compounds in water or the atmosphere are other potential environmental stressors capable of changing epigenetic status.
Detailed explanation-3: -Which of the following statements is true about epigenetics? Epigenetics involves heritable changes to DNA that are independent of the genetic sequence yet influence its expression.
Detailed explanation-4: -The Oxford dictionary defines epigenetics as ‘the study of changes in organisms caused by the modification of gene expression rather than alteration of the genetic code itself.
Detailed explanation-5: -The epigenetics does not involve a change in the sequence of DNA. This sequence of DNA cannot be altered permanently. The given statement in this option is false, hence this option is the correct choice.
