An RNA polymerase II molecule is about 15 nanometers across, or roughly 5,000 times smaller than the width of a human hair. This image was created by reconstructing X-ray diffraction crystallography ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure ... RNA through the process of ...

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...
