Do genes have a role to play in epigenetics and variations in epigenetic patterns between individuals? Explain your answer.
Step by step
Solved in 2 steps
- Explain the term Epigenetics ?What are epigenetic modifications? a. the addition of reversible changes to histone proteins and DNA b. the removal of nucleosomes from the DNA c. the addition of more nucleosomes to the DNA d. mutation of the DNA sequenceDo different genes affect epigenetics and variations in epigenetic patterns between individuals?
- A scientist does an experiment in which she removes the offspring of rats from their mother at birth and has her genetics students feed and rear the offspring. Assuming that the students do not lick and groom the baby rats as the mother rats normally do, what long-term behavioral and epigenetic effects would you expect to see in the rats when they grow up?explain how the discovery of epigenetic factors has changed the way we think about characteristics that can be passed from one generation to another.Are all of your genes expressed in every cell in your body? Explain your answer and include an example in your explanation.
- Define epigenetics. Are all epigenetic changes passed from parentto offspring? Explain.Explain about the epigenetic differences ?Discuss the similarities and differences of phenotypic variations that are caused by epigenetic gene regulation versus variation in gene sequences (epigenetics versus genetics).
