Transcription- Vanessa Torres

Transcription

          Transcription deals with DNA and RNA. Transcription is the process of making an RNA copy from o portion of DNA strand. DNA safely and stably stores genetic material in the nucleotide of cells as a reference or template. The first step to transcription is to have the enzyme unzip the DNA molecule, next you free RNA nucleotide from the base pairs with complementary nucleotides, lastly the mRNA strand then breaks away and the two DNA strands rejoin again.
       Although RNA polymerase traverses the DNA template strand from 3 to 5, the coding strand is usually used as the reference point. Unlike DNA replication transcription does not need a primer to start and it uses base pairing to create an RNA copy containing uracil instead of thymine. 
         I had a hard time understanding transcription first, but once I got the hang out the process of it it was super easy to me.
