The understanding and manipulation of DNA replication hold significant opportunities for:

  • DNA replication is a linear process: while the synthesis of a new strand is a linear process, the unwinding and initiation steps are complex and involve multiple enzymes.
    • Telomeres are the protective caps on the ends of chromosomes that shorten with each cell division. During DNA replication, telomerase extends the telomeres to prevent chromosome shortening.

    Opportunities and Realistic Risks

  • Unwinding the Double Helix: The first step in DNA replication is to unwind the double helix structure of DNA. This is achieved by enzymes that break the hydrogen bonds between the two strands.

    • DNA replication is the process by which a cell makes an exact copy of its DNA before cell division. This process involves several key steps:

      • How accurate is DNA replication?
      • Ligation: Finally, the new strand is sealed by an enzyme called DNA ligase, which forms a phosphodiester bond between the nucleotides.
      • Synthesis of a New Strand: Once the double helix is unwound, an enzyme called primase adds short RNA primers to the template strands.
      • Personalized medicine: tailored treatment plans based on an individual's genetic profile
      • DNA replication is always 100% accurate: while DNA replication is generally accurate, errors can occur, and these errors can lead to mutations.
      • Elongation: DNA polymerase, the enzyme responsible for adding nucleotides to the growing strand, reads the template strand and matches the incoming nucleotides to the base pairing rules (A-T and G-C).
