We still need to clear up one or two points of nomenclature in normal replication of nucleic acids, the matrix (the + strand) and the newly formed daughter strand (- strand) are held together by Watson-Crick hydrogen bonding. This process is also referred to as cross-catalytic . Normal autocatalysis is different it leads to a product which corresponds in structure to the matrix, so that there is no difference between the + and - strands. Such self-complementary sequences are called palindromes.
