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.

Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs - even arthropods, with six, eight or more limbs, walk.
