The Basics: How Ethanol Precipitation of DNA and RNA WorksOswald, Nick
How does RNA help in protein synthesis? How are transcription and replication similar? Why can RNA bind to DNA? In what way does RNA polymerase differ from DNA polymerase? How does DNA get turned into RNA? How do RNA and magnetic beads bind together when performing RNA extraction?
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 ...
Structure of a DNA:RNA hybrid duplex. Why RNase H does not cleave pure RNA. The solution structure of the DNA:RNA hybrid duplex d(GTCACATG):r(caugugac) has been determined by means of two-dimensional nuclear Overhauser effect (2D-N... OY Fedoroff,M Salazar,BR Reid - 《Journal of ...

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 ...

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...
