DNA in the nucleus is mixed as oil with water and soap
Most cells of human body have DNA packaged and folded inside of their nuclei. The process of transcription, which also takes place in the nucleus, partially unfolds and redistributes DNA in a very distinct pattern. In a collaborative work, we have shown that the emergence of this pattern can be explained by the physical model of a microemulsion, very similar to the mixture of water, oil and soap.
