Nucleic Acids: DNA and RNA
We've been hearing about DNA since the third grade, and we all know that it's a double helix with little ladder rungs. But now we are ready to understand this molecule on a more fundamental level, which will enable to us to understand...

DNA uptake by a cell, animation.
In this process, a foreign strand of DNA (blue) enters the cell, and the cell's colour changes to match that of the new DNA, indicating that genes in the new DNA are being expressed. There are numerous examples of new DNA being...
