Part of thechromosome's tightly wound-up long strand of DNA is "loosened" to allow for RNA polymerase room to copypart of the DNA. Think of this as opening a page out of a giant book with thousands of pages to make a copyof just that one page. One side of the DNA strand is the template strand (or anti-sense strand) and is used by anenzyme called RNA Polymerase to create the messenger RNA. RNA Polymerase is directed by a bunch ofproteins called transcription factors to the spot it needs to start copying. RNA Polymerase reads the templatestrand from the 3' end to the 5' end and creates a messenger RNA strand that is complementary to the templatestrand. In the diagram above, you can see that the growing RNA strand has uracil instead of thymine becauseRNA nucleotides do not use thymine as a base. Anywhere there is an adenine nucleotide in the DNA, thecomplementary RNA strand will have a uracil. Nucleotides are always added to a growing strand by connectingthe 5' end of the new nucleotide to the 3' end of the growing strand. The other strand of the DNA is called thesense strand and is not used for this particular transcription event. When the messenger RNA is completed, itlooks almost identical to the sense strand; only thymine(T) is replaced by uracil(U).The area of DNA that is copied into a messenger RNA is called a gene. Each chromosome has many genes,sometimes thousands of genes but in between these genes are sections of DNA that are not transcribed intomessenger RNA copies. Scientists are studying the process of transcription to figure out what is importantabout these non-gene regions. They may be important for telling RNA polymerase where to go to find genes.(C) 2015 Bethany Lau.
