Abstract excerpt

The ubiquity of satellite DNA (satDNA) sequences has raised much controversy over the abundance of divergent monomer variants and the long-time nucleotide sequence stability observed for many satDNA families. In this work, we describe the satDNA BIV160, characterized in nine species of the three main bivalve clades (Protobranchia, Pteriomorphia and Heteroconchia). BIV160 monomers are similar in repeat size and...
