Source sentences:
text: The centromere is usually defined by specific DNA sequences which are in higher eukaryotes typical tandem repetitive sequences, often called "satellite DNA".
text: Simple eukaryotic organisms, such as budding yeast, have point centromeres, defined by a specific DNA sequence found on all chromosomes (see below), whereas more complex eukaryotes have larger regional centromeres that are defined by hierarchical arrays of satellite repeats.
