Magnetic activated cell sorting (MACS) with annexin V microbeads recognizes externalized phosphatidylserine (PS) residues on the surface of apoptotic spermatozoa. The successful use of this novel technique applied to a highly apoptotic semen sample before performing intracytoplasmic sperm injection (ICSI) is reported here. DNA polymerase δ synthesizes and adds dNTPs at 3’ end of RNA primer. The leading and lagging strands are synthesized in the similar fashion as in prokaryotic DNA replication. Termination: At the end of DNA replication the RNA primer are replaced by DNA by 5’-3’exonuclease and polymerase activity of DNA polymerase ε.

- A-DNA: It is a right-handed double helix similar to the B-DNA form. Dehydrated DNA takes an A form that protects the DNA during extreme condition such as desiccation. Protein binding also removes the solvent from DNA and the DNA takes an A form. B-DNA: This is the most common DNA conformation and is a right-handed helix. Majority of DNA has a B.
- Recombinant DNA, molecules of DNA from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry. Recombinant DNA technology was first developed in the 1970s.
