The Basics: How Ethanol Precipitation of DNA and RNA WorksOswald, Nick
How does RNA help in protein synthesis? Why can RNA bind to DNA? How is DNA structure similar to a protein? How does an RNA virus replicate? What makes RNA a unique nucleic acid? How does transfer RNA work? How is protein synthesis different from DNA replication?
How are DNA, RNA, and proteins related in the cell? How DNA replication occurs? Where is DNA located in a cell? How is DNA replicated? How does the structure of DNA differ from that of RNA? How does DNA replicate? How does DNA unfold itself in space during reproduction?
Finally, from the DNA of one cell, we can clone an animal, a plant or perhaps even a human being. But what is DNA? Where is it found? What makes it so special? How does it work? In this article, we will look deep into the structure of DNA and explain how it makes itself and...
A synthetic DNA enzyme catalyses the formation of a native phosphodiester bond between two RNA fragments, but the molecular details of the mechanism remained elusive. Research using computational and biochemical approaches now suggests that the DNA enzyme recruits two magnesium ions to assist in the ...

How Does the CRISPR-Cas System Work? CRISPR is the coolest technology in a biologist’s toolbox because of its unique blend of being extremely powerful yet relatively simple to use. The technique relies on two basic components: a Cas nuclease that cuts the DNA and a guide RNA that tells ...
This can be done by simply mixing the coat protein subunits and the viral RNA-based sequences in defined ratios under conditions selected by the experimenter. How closely the selected conditions resemble those within an infected cell is open to question. However, a potentially even more critical ...
In any biological system with memory, the state of the system depends on its history. Epigenetic memory maintains gene expression states through cell generations without a change in DNA sequence and in the absence of initiating signals. It is immensely powerful in biological systems — it adds lon...
