Sažetak
Satellite DNA sequences have been characterized in species of the genus Palorus. Despite insignificant sequence homology, all the satellites exhibit sequence induced curvature of DNA helix axis. The results explain satellite DNA evolution confirming the hypothesis that related species share a library of satellite sequences some of which could be amplified into a major satellite. Interspecific conservation of satellite sequences points to the very low substitution rate, which is in contrast with a high rate of sequence change proposed for noncoding DNA. Low rate of satellite sequence change might be related to their heterochromatic location, or due to selective pressure necessary to conserve some feature of functional significance.
