Why are nucleotides crucial to cell regeneration?
The cell replication process explained
Before cells can divide or reproduce, they must make a copy of (replicate) the genetic information contained in their DNA. It is essential to the well-being of our bodies that this replication of genetic information is exact as any errors can result in a loss of immunity, disease or even genetic mutations.
To complete the complicated process of error-free DNA replication each cell needs access to, amongst other things, a pool of freely available, relevant nucleotide bases to build the copy from and a supply of RNA and various enzymes (nucleotide-containing molecules) to stimulate and provide energy for reactions.
During replication, the existing double helix structure uncoils, and at certain points (origins) along the pattern of nucleotide pairs it “unzips” itself lengthwise so that each side of the DNA strand is exposed at the middle (see figure 1).
While unzipped, the two complimentary halves of the nucleotide pattern are exposed so that any freely available nucleotides can be matched up, in their relevant pairs, to create two identical versions, each containing one half of the original genetic template.
The fact that these nucleotide bases can only pair up in certain combinations ensures that the two emerging strands of DNA are identical to the original template. The complicated process of cell division or reproduction can only now proceed unhindered.

The importance of a balanced supply of nucleotides
Without a balanced pool of all five major nucleotides, stockpiled and ready-for-use, cellular replication could be delayed or put on hold indefinitely until the required nucleotide is produced or made available for use.
In future articles we will discuss the different ways in which the body can meet this demand for a balanced pool of all five major nucleotide bases.
