A DNA template is used to create an mRNA strand.

Explanation: Transcription is the first step in the formation of a long chain of aminoacids, a protein. I toccurs when a product of a particular gene at specific time and place is needed. In that specific area, the DNA opens up and only one strand of DNA is copied. This single strand is called Template. The transcription process is carried out by the enzyme RNA polymerase: First, it recognizes a specific sequence on DNA called promoter. This is the indicator of the beginning of the gene. The two strand of DNA separates and RNA polymerase begins copying using a special type of sugar called ribonucleoside 5'-triphosphate. Each ribonucleotide is paired to its complementary: C (citosine) with G (Guanine), T (thymine) with A (adenosine) and A with U (uracil). This last base is the main difference between DNA and RNA. The process contniues until a sign of termination is detected, releasing the RNA, now called RNA messenger.

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.
