The larger, more complex variety are known as composite and consist of a central portion, possibly containing functional genes, flanked by insertion sequences at either end.
The larger, more complex variety are known as composite and consist of a central portion, possibly containing functional genes, flanked by insertion sequences at either end. The simplest types are known as insertion sequences and typically consist of 700-1500 base pairs with numerous short repeated nucleotide sequences at either end. These mobile genetic elements can disrupt gene expression or cause deletions and inversions, and account for a sizable portion of the repetitive DNA in eukaryotes. FTP, identify these features discovered by Barbara McClintock and also known as "jumping genes."
