summary:a man named Levinson and he belives that kidney cells transporting ions, and could be well suited to making a miniature battery.He suggests that such biobatteries might be ideal for powering devices inserted in the body, such as insulin pumps or pacemakers.and so he went for it
Questions: What reactions does this enzyme catalyze?it transports ions to the kidney
How is the cell affected if this enzyme is removed? i think it effects it in a bad way because the ions are needed for transporting information

Summary:Each DNA strand includes a sugar and phosphate "backbone" attached to one of four bases, which encode genetic sequences. The strength of the interactions within individual strands comes largely from the chemical attraction between the stacked bases. But the integrity of double-stranded DNA depends on both the stacking forces between base units along the length of the double helix and on the pairing forces between complementary bases, which form the rungs of the twisted ladder.
