“Planimal” cell chromosomes

Caption

This fluorescence microscopy image shows DNA from the unicellular red alga Cyanidioschyzon merolae (schyzon), shown in green, integrated into hamster chromosomes stained blue. Algal-derived DNA was detected at specific sites on hamster chromosomes, demonstrating physical association between the two genomes. The transferred algal DNA was stably inherited through repeated cell divisions. The magenta signals indicate the distribution of repetitive DNA sequences naturally present in hamster chromosomes.
