down the middle
To split DNA strands to create doubles.
The stage at which a DNA molecule is split down the middle is replication. The first step in making a protein is RNA copying DNA.
These are called Single Stranded Dna or ssDna.
cell makes exact all DNA in order to split into two cells.
Nope, it is a 50/50 split.
helicase
To reproduce for your changing body.
Dna is split up into two different strands of nucleotides. After that is beyond me.
Bacterial DNA is single strand. Human DNA in the nucleus is double helix. So, with human DNA, the DNA must first split apart before an RNA molecule can read it.
So then the cell can split the replicated DNA into to nuclei and then form two separate cells, each with their own nucleus and own set of DNA.
It splits down the middle due to the action of the enzyme helicase. This exposes the nitrogen bases on both strands of the DNA.
