For nuclei larger than 4He, protons (P) and neutrons (N) are basically bound alternatively to form a ZP + ZN 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 "...
the tiny creatures carry a unique protein called Dsup, which is a contraction of the phrase "damage suppressor." While it might sound like some sort of health boost upgrade in a video game, Dsup is a nuclear protein that binds to a section of DNA inside the nucleus called nucleosomes, th...
If you’re looking to make a Google Home speaker the center of your smart home, you may want to consider that its compatibility with other products is more limited than Amazon’s (though it’s still quite huge). There aren’t enough buttons on the simple speaker models (for that you’...
A nuclear power plant works pretty much like a conventional power plant, but it produces heat energy from atoms rather than by burning coal, oil, gas, or another fuel. The heat it produces is used to boil water to make steam, which drives one or more giant steam turbines connected to ...

Label each organelle on the diagram and draw each using a different color. Step 4 Draw the cell membrane, which will be the outline of the cell. Step 5 Draw the cytoskeleton. This includes the filaments and microtubules. Step 6 Make the oval-shaped nucleus with the nucleolus in its center...
First, there’s old-school, Dolly-the-sheep cloning, which involves taking a whole genome from the DNA of your target species and injecting it into an egg of a closely related species that is minus its nucleus, and coaxing it to develop. Ice is far better at preserving DNA than the am...

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...
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...
