- RNA polymerase
binds to DNA
at a specific region called the promoter site and separates
the double helix to single strands.
- One of the DNA
strands on the gene is used as a template
on which RNA
nucleotides are built, using the base-pairing rules.
- Uracil (U) pairs with Adenine (A).
- Non-coding regions of the gene (introns)
are copied along with coding regions.
- The mRNA transcript
is released when it reaches the end of the gene.
- The intron portions of the transcript
