Summary
... Summary Learning and memory are fundamental processes for animal survival. Memory stabilization is mediated by long-lasting modifications of synapse strength and structure. This is known as synaptic plasticity and may occur at either side (pre- or post-) of the synapse. The main objective of this th ...

Now the line between these two components is blurred by inherited epigenetic variation. 2. How widely exist about the inhe ...

Epigenetics: We often discuss genes as if their presence in our cells

Chemical signals in this region - most commonly the addition of a methyl group (methylation) - can essentially instruct the RNA polymerase that would otherwise transcribe a gene to skip the gene with the methylated pr ...

Understanding Heritability and Epigenetics

It is the study of how variation in inherited traits can originate through means other than variations in DNA. Epigenetics refers to the epigenome.
