The body synthesizes DNA through a complex process involving various enzymes and biological mechanisms. Here's an overview of the key enzymes and processes involved in DNA synthesis based on the provided search results:
DNA polymerase also functions as a self-correcting enzyme, removing its own polymerization errors as it moves along the DNA
Primase:
DNA polymerases can only add nucleotides to the 3' end of an existing DNA strand. To initiate DNA synthesis, an enzyme called primase makes an RNA primer, or short stretch of nucleic acid complementary to the template, that provides a 3' end for DNA polymerase to work on. Once the RNA primer is in place, DNA polymerase extends it, adding nucleotides one by one to make a new DNA strand that's complementary to the template strand
Terminal Deoxynucleotidyl Transferase (TdT):
TdT is a DNA polymerase that requires no template and is used in enzymatic DNA synthesis. It is involved in the synthesis of DNA and has been a key focus in the development of enzymatic DNA synthesis strategies.
Helicase:
Unwinding of DNA at the origin and synthesis of new strands, accommodated by an enzyme known as helicase, results in replication forks growing bi-directionally from the origin. Helicase unwinds the double helix at the replication fork, allowing DNA polymerase to access the single-stranded DNA for replication
DNA Ligase:
DNA ligase is involved in the repair and replication of DNA. It plays a crucial role in linking the DNA fragments together by catalyzing the formation of phosphodiester bonds between the adjacent nucleotides, thus joining the DNA strands
