Once the bonds between the dsDNA strands are broken they will not be able to be reformed. On the other hand, generally other salt denaturing methods cannot be reversed. The benefit of using NaOH to denature DNA is that it can be renatured by the addition of phosphate buffer. Denaturing with NaOH can take great amounts of time depending on the concentration of the chemical. However, it is not the most accurate method and the use of DNA sequencing might be a better substitute for it. Heat denaturing is the most simple and the easiest way to undergo the splitting of the dsDNA. When the strands are separated, the heat is removed or the mixture is neutralized in order to prevent the strands from rejoining together. This is also the best way to split DNA as it usually results in two, whole single-stranded DNA chromosomes. These are called the denaturation of DNA. These can range from treatment with salt or NaOH as well as direct heating methods. When dsDNA is artificially separated and forms ssDNA – There are numerous artificial methods used to separate dsDNA to form ssDNA. Some examples of these kinds of viruses are Canine parvovirus – a contagious parvoviridae virus that affects dogs and Bdellovibrio bacteriovorus – a microviridae that is a host-dependent bacterium. Seawater, marine microbial mats, extreme environments, freshwater, terrestrial environments, metazoan-associated mats and sediments are all places where these viruses that contain single-stranded DNA can be found. These viruses have DNA that does not need or have two strands that will complement each other and so bind together, leaving them as single-stranded DNA genome viruses. This is present as simple - just a strand of nucleotides that is very long.
