For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

Understanding the non-coding portion of our DNA is ... it matters which of the two DNA strands you target. "Depending on ...

To accomplish this, each strand of existing DNA acts as a ... and anti-sequence copying that preserves the coding of the original DNA. In the prokaryotic bacterium E. coli, replication can occur ...

Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain (Figure 2b). At a temperature of ...

The enzyme RNA polymerase attaches to the DNA in a non-coding region just before the gene. RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA ...

Various non-coding RNAs also play important roles in regulating gene ... In this process, the enzyme RNA polymerase uses one strand of the DNA as a template to synthesize a complementary RNA strand.
