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 ...
a single strand of DNA sequence has three possible reading frames. Long ORFs may indicate candidate protein coding regions in a DNA sequence.
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.
