Epigenetics is like the baton of an orchestra conductor that gives instructions for interpreting the notes (genes) of our DNA!
Epigenetics is like the baton of an orchestra conductor that gives instructions for interpreting the notes (genes) of our DNA! Imagine that in each cell of your body, you have an identical musical score (DNA). As far as epigenetics is concerned, that’s it that decides how to play this score for each of the instruments (cells).
The notes (genes) are not modified and the score (DNA) remains the same, but the way in which the notes (genes) are played will modify the sound (expression of genes) of each instrument (cell). They can leave some instruments (cells) playing loud and others behind, creating a unique symphony based on an identical score (DNA).
Simply put, epigenetics makes our genes versatile artists, able to shine or stay behind as needed. This is what allows our body to function harmoniously. Each cell thus playing the perfect biological score of a body directed by the baton of a talented conductor. It's a bit as if each cell knew its score but played it in such a way as not to modify the original melody. This is the amazing magic of epigenetics!
Speaking of epigenetics as a musical score, the musical notes would be the different chemical marks and modifications present in and around our DNA.
Think of these notes as the nuances, crescendos, and diminuendos that bring the melody of our genome to life. Here are some of these epigenetic musical notes:
1/ DNA Methylation (M):
Think of an “M” as a note that tells the instrument (the cell) to play louder or softer. Methylation can turn
certain genes on or off, thereby modulating gene expression.
2/ Histone Acetylation:
Histones are like musicians in an orchestra, and acetylation is an indication that tells them to play louder or quieter. This affects how DNA wraps around histones and thus influences gene accessibility.
3/ Non-coding RNAs:
These RNAs are like complementary melodies that are superimposed on the main score. They help regulate gene expression by changing the way genetic messages are interpreted.
4/ Epigenetic inheritance:
If we continue with our musical metaphor, epigenetic inheritance would be like the transmission of a musical style from one generation to another. Epigenetic modifications can sometimes be inherited, influencing the way music is played within the family of cells.
5/ Responses to environmental factors:
Environmental noises can be like sudden disruptors of the melody. Factors such as diet, stress or exposure to toxins can disrupt music to the point where it can become inaudible, altering the genetic symphony.
In summary, the musical notes of epigenetics are chemical markers and processes that modulate the expression of our genes, creating a complex and adaptive biological symphony. Each note contributes to the diversity and plasticity of the genetic music that makes up our body.
