1 DNA is a polymer. 2  Individual monomer units are called nucleotides. 3  The DNA polymer is composed of: 4  a backbone of molecules of the sugar deoxyribose (a 5 carbon sugar). 5  phosphate groups linking the deoxyribose sugar molecules together in a chain.

Rods and cones function as photoreceptors in the retina of the eye, turning visible light into neuronal signals, which are sent to the brain. This process is called transduction. Rods and cones perform at different wavelengths and sensitivities allowing detailed perception of light and color.
How do Control Rods Actually Work? I know the layman terms from Wikipedia like the rods are filed with neutron absorbing material to absorb the neutrons, thus slowing down, or in SCRAM, stopping the reaction to a negligible point. But I want to know the more in dept stuff, what are they made out of, how they work, etc, etc. Just ell everything you...
