1 Oranges, tangerines, grapefruit, lemons, and limes have the highest detoxifying effects. You can eat them on their own or combine them with other fruits. Again, do not exceed 7 days in a row of a fruit-only diet.  Try a grape detox.
DNA polymerase adds nucleotides onto the 3'OH end of the preceding nucleotide and carries out synthesis in the 5' to 3' direction down the length of the DNA. The result of DNA polymerase function is two copies of DNA that contain one original and one newly synthesized strand of DNA.
What is the function of DNA polymerase I? Proofreads DNA. (about 20 at a time before it dissociates). It is a 5' to 3' DNA polymerase but also has 5' to 3' and 3' to 5' exonuclease activity to proof read and correct mismatches. It works with DNA:DNA as well as RNA:DNA.
