We are at the beginning of this endeavor and much work remains to be done but already it is clear that imprinted genes have the potential to influence diverse behavioral processes via multiple brain mechanisms. There are also grounds to believe that imprinting may contribute to risk of mental ...
How do imprinted genes affect offspring? What role do mutations play in natural selection? What is the relationship between genetic mutations and cancer? Is TP53 mutation genetic? What is non-Mendelian genetics? What is caused by an autosomal dominant mutation?
What is the role of topoisomerase in DNA replication? What is the role of DNA methylation in regulating transposons (Transposable Elements, TEs; "jumping genes")? What role does DNA play in phenotypic expression in organisms? What is the role of primase in DNA synthesis? What is th...

An example of this is from Catherine Dulac's group in which they investigated the genetics of sex differences in the brain by comparing parent-of-origin allelic gene expression and found that imprinted genes inherited from maternal or paternal origin were dependent on the offspring sex as Box 1...
We know that a predisposition to become overweight is found in our genes. Now, we’re starting to learn thatepigeneticsalso has a hand in determining whether a person will become fat or lean. New research is uncovering the possibility of an epigenetic switch that is, interestingly, either “...
Though we consciously seek only the positive traits, the negative traits of our caretakers are more indelibly imprinted in our Imago picture, because those are the traits which caused the painful experiences we now seek to heal. Our unconscious need is to have our feelings of aliveness and who...

What is the difference between DNA, chromatin, and chromosomes and what is the significance of each form? What is the human genome, and how would one explain it using haploids and chromosomes? Define guanine and cytosine. Describe what is meant by an imprinted gene or imprinted piece of DNA...
