Exam 8: The New Frontier - Behavioral Epigenetics or How Nurture

Which process blocks the transcription (copying) process, "turning off" expression of that gene?

Although changes resulting from epigenetic mechanisms can persist and may even be inherited, some of these changes can be reversed, known as:

In 1859, who published Origin of Species, a seminal book that became the foundation for the modern science of genetic evolution, sociobiology, human behavioral ecology, and evolutionary psychology, among others?

It is probably the case that all epigenetic changes are reversible.

Health disparities tend to occur in clusters, considered which type of phenomena?

Which process is not so much an "off-on" process as it is like a dimmer switch?

Changes resulting from epigenetic mechanisms can persist and may even be inherited-passed on to the next generation.

The key for which of the following is that a wide range of environmental factors, from many layers of a person's social ecology, can affect DNA methylation/demethylation and histone modification for specific genes as part of the process of translation and transcription?

Histones have "tails" capable of receiving signals that can either loosen up the packed DNA strands, making them more available for copying, or keep them wrapped up tightly and thus less available for copying.

Health disparity communities and populations are exposed to higher levels of the kinds of environmental factors that produce epigenetic changes associated with health risk.
