Topic 4: Key Points
In this section, we explored the following main points:
In this section, we explored the following main points:
- Epigenetic mechanisms may influence gene expression without alteration in the DNA sequence.
- Main epigenetic mechanisms are DNA methylation, histones post-translational modification and alteration in the expression of microRNAs.
- Epigenetic change is a regular and natural occurrence but can also be influenced by several factors including age, the environment/lifestyle, and disease state.
- Different from genetic alterations, epigenetic alterations are considered reversible.
