SSBs maintain the separated strands during DNA replication. Without the SSBs, the complementary DNA strands could easily snap back together. SSBs bind loosely to the DNA, and are displaced when the polymerase enzymes begin synthesizing the new DNA strands.
Scientists can then add DNA sequences (i.e. a particular gene of interest) to this exposed strand using an enzyme called DNA ligase. When the DNA strand is repaired this recombinant DNA will create the protein product of the new gene. Any form of DNA can be spliced together, no matter what its origin. For example, human insulin-producing genes have been spliced into plasmids.
