Question

Quizplus · Accepted Answer

Epigenetic effects refer to modifications in gene expression without any alteration in the DNA sequence of genes. These modifications can occur in response to environmental factors and can be passed on to offspring. They include DNA methylation, histone modifications, and RNA-associated silencing. These modifications can activate or repress gene expression, leading to changes in an organism's phenotype. The occurrence or structure of genes is determined by the DNA sequence itself, and epigenetic effects do not alter this. Therefore, choice A - expression of genes is the most accurate answer.
