One of the most important reasons for only using reliable water source is to reduce?

The right answer is The number of parasites, such as Cyclospora Cayetanensis.

The health risks associated with water are due to the use of polluted water, unfit for the intended use, for example:

- Consumption of water (beverage, ...), live products or products grown in aquatic environments (shellfish, ...);

- Swimming ;

- Use in a hospital environment (hot water, ultra pure water, ...).

Depending on the pollutants, the health risk is of an infectious nature (viruses, bacteria, parasites, fungi), chemical (mineral, organic), or physical (thermal, radioactive).

The risks involved are more or less long term. Some are known and proven for health, and others are suspected or even emerging.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
