Which statement best summarizes what happens during transcription? a dna template is used to create an mrna strand. an mrna template is used to create a dna strand. a dna template is used to create a ribosome. an mrna template is used to create a trna strand.

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.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
