DNA replication of Eukaryotes (cells with a nucleus) occurs stepwise. Each step needs different enzymes. The DNA replication steps can be broken down as: A notch is made by DNA gyrase. This looks like a bubble under a microscope, called Replication Bubble. Cracking up the hydrogen bonds in the double helix is the vital step and it occurs where more A-T bases exist.
Walking - or doing any effort with our muscles with that matter - converts chemical energy into mechanical energy. We get the chemical energy from the food we eat.

â¢ Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. â¢ Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy. â¢ Thermal energy cannot do work, but mechanical energy can do work. â¢ Mechanical energy has two main forms, namely kinetic energy and potential energy.
