The two strands of DNA are held together by weak hydrogen bonds (remember, something must hold them together!) between the nitrogenous bases. The interesting (and very important) aspect of the Watson-Crick model is that these hydrogen bonds are base specific.
NEW STRAND SYNTHESIS. Now that they are separated, the two single DNA strands can act as templates for the production of two new, complementary DNA strands. Remember that the double helix consists of two antiparallel DNA strands with complementary 5â to 3â strands running in opposite directions.he point where the DNA is separated into single strands, and where new DNA will be synthesized, is known as the replication fork. Single-strand binding proteins, or SSBs, quickly coat the newly exposed single strands. SSBs maintain the separated strands during DNA replication.
