The trunk of each 'Christmas tree' (a transcription unit) represents a DNA molecule; the tree branches (granular strings attached to the DNA) are RNA molecules that have been transcribed from the DNA.

At different times during the life cycle of a cell, the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more ...

Purification removes contaminants from DNA samples, ensuring the integrity of the genetic material and providing more ...

During replication, DNA polymerases are positioned on each strand of DNA. Using a microscope slide as an anchor, we tethered DNA to a bead and stretched it with a flow of solution. We tracked how the ...

Call it the science of small, but a trio of University of Florida chemical engineers have developed a lab-on-a-chip process ...

The new finding is published in Cell in an article titled, “ SMC motor proteins extrude DNA asymmetrically and can switch directions ,” and is key to understanding how these motors shape our genome ...
