Atemplate strand of dna is read in the direction in order to direct synthesis of rna in the direction.

The RNA synthesis or ADN transcription occurs in the nucleus and requires:
  - DNA strand to act as a template.
  - Enzymes, specially the RNA-polymerase.
  - Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

Very minute and important evidence needs to be collected in order together detail and figure out what had happened
