Modern Chemistry Chapter 6 Chemical Bonding Test Answer Key

DNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 angstroms (Å) (3.4 nanometres).

Physics (from Ancient Greek: φυσική (ἐπιστήμη), romanized: physikḗ (epistḗmē), lit. ‘knowledge of nature’, from φύσις phýsis "nature") is the natural science that studies matter, its motion, and behavior through space and time, and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is.
