Standard genetic sequencing approaches can tell you a lot about the genetic makeup and activity in a sample, like a piece of ...

What if you could take a picture of every gene inside a living organism—not with light, but with DNA itself? Scientists at ...

DNA is always synthesized in the 5'-to-3' direction, meaning that nucleotides are added only to the 3' end of the growing strand. As shown in Figure 2, the 5'-phosphate group of the new nucleotide ...

At this point, RNA polymerase begins moving down the DNA template strand in the 3' to 5' direction, and as it does so, it strings together complementary nucleotides. By virtue of complementary ...
