This suppression of recombination allows alleles adapted to a specific environment to remain together, unshuffled by recombination

If entire genome is encoding than mathematically human should have 106 genes but humans have only 30,000 to 50,000 genes this is also a paradoxical feature of genome

1. DNA polymerase I is a single polypeptide of 103 kD. 

2. 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. 

3. It contains the polymerase and the proofreading 3’–5’ exonuclease activities.

The products of the catalytic cycle are either two molecules of 3-phosphoglycerate (carboxylase activity) or one molecule each of 3-phosphoglycerate and 2-phosphoglycolate (oxygenase activity).

PNPase a 3’ to 5’ exonucleases in E. coli, are unable to progress through double-stranded regions. Thus, the stem-loop structure at the 3’ end of many bacterial mRNAs protects the mRNA from direct 3’ attack.
