For nuclei larger than He, protons (P) and neutrons (N) are basically bound alternatively to form a P + N ring. The ring folds with a "bond angle" of 90掳 for every 3 continuous nucleons to make the nucleons packed densely. Extra N('s) can bind to ring-P with the same "bond...
So, you know you need 6 protons to make a model of carbon. To make a carbon atom, make 6 protons, 6 neutrons, and 6 electrons. Bundle the protons and neutrons together to make the nucleus and put the electrons outside the atom. Note that the model gets slightly more complicated when ...
The number of Astronomy related Internships/Summer Schools/Camps/Conferences are endless, thus this will provide a beginning to your search of things to do in those long summer holidays (or simply if you just want to go off and explore another country). I’ve tried to make sure that most ...

Remove the gelatin from the refrigerator and open the bag. Insert small pieces of candy and fruit into the gelatin to represent the cell's internal parts, such as the nucleus, mitochondria and ribosomes. Step 5 Reseal the plastic bag and place it back in the refrigerator. The gelatin will...
DNA, likeRNA, is a type of macromolecule known as anucleic acidthat contains the genetic information for the reproduction of life. DNA is coiled intochromosomesand tightly packed in thenucleusof ourcells. Its shape is that of adouble helixand its appearance is somewhat of a twisted ladder or...

Unfortunately, these agents face a difficult hurdle. The raw material (amino acids) and the factory (ribosome) required to build the machines (proteins) are both found outside the HQ (nucleus). That may not initially seem like a problem, as the DNA could simply be taken outside the nucleu...
