The water reclamation, the greywater usage, and the desalination processes are kind of similar, but also kind of different.
The water reclamation is a process in which the wastewater through chemical and biological treatments is cleaned from the polluters, so that it can be returned into the environment and not cause any damage.
The greywater is a wastewater from the households and offices that doesn't have fecal contamination. This water is not suitable for drinking, but it is also not in a very bad state, so it is used for the toilet flushing, laundry washing, for irrigation.
The desalination is a process through which the saline water is stripped of the salt, in order to be suitable for drinking. This is not a widely used process, but some places like the countries on the Arabian Peninsula have to do it because there is not a single stream or river with freshwater with constant flow.

Answer:
to add nucleotides to a DNA primer
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology in order to amplify small segments of DNA (100 to 1000 bases). PCR uses a thermostable DNA Taq polymerase that adds nucleotides to the DNA template at the position specified by short single-stranded DNA primers that bind to this template by complementary base pairing during the annealing phase of the PCR cycle. Subsequently, the DNA polymerase adds deoxynucleotide triphosphates (dNTPs) to the opposite DNA strand, this phase of the PCR cycle is known as the elongation phase. Finally, the resulting double-stranded DNA fragment is separated by heat during the denaturation step and this 3-step PCR cycle is repeated many times to amplify the target DNA region.
