We travel inside nucleus to see how the DNA replicates.

When DNA replicates its strands are separated by enzine helicase.
Single-stranded DNA binding proteines keep the strands from...

This video shows how various molecules look. For example, water consisting of two hydrogen atoms and one oxygen atom.

The others are: glucose, sucrose, amylose, stearic acid, oleic, glycerol,...

First the DNA Wrapping is animated.
The wrapping allows 6 feet of the long DNA molecule to be densely packed into the tiny nucleus of every cell. The process starts when DNA is wrapped around...
