Chromosome satellite for American and Chinese chestnut species

Caption

Chromosome satellite for both species (Chinese chestnut on the left, American chestnut on the right). Like all chromosomes, these are made of chromatin – a mix of DNA molecules and proteins. There are several types of chromatin. The bright blue tip in the Chinese chestnut indicates heterochromatic DNA, and the lighter purple color on the tip may represent the euchromatic DNA. The entire region of the American chestnut satellite appears to be euchromatic.
