The first DNA-synthesizing enzyme to be characterized was DNA polymerase I, which is a single polypeptide of 103 kD, The chain can be cleaved into two parts by proteolytic treatment.

The larger cleavage product (68 kD) is called the Klenow fragment. It is used in synthetic reactions in vitro, It contains the polymerase and the proofreading 3'-5'  exonuclease activities.

The small fragment (35 kD) possesses a 5 '-3' exonucleolytic activity, which excises small groups of nucleotides, up to - 10 bases at a time. This activity is coordinated with the synthetic/ proofreading activity. It provides DNA polymerase I with a unique ability to start replication in vitro at a nick in DNA.

Phytovolatilization

Plants remove inorganic contaminants· either by contaminant volatilization or by metal accumulation.

Volatalization is useful for the removal of mercury. A bacterial mercuric ion reductase has been transferred to Arabidopsis thaliana; this transgenic plant absorbs mercury, and reduces it to volatile Hg0, which volatilizes from the leaf surface.
