The most important type of lens is the biconvex spherical lens.
For an example, see E. Coli K-12 MG1655 operon thrLABC.
Multiple different transcription units can be produced by a single operon, see: operon vs transcription unit.

Interesting because of the Cook-Levin theorem: if only a single NP-complete problem were in P, then all NP-complete problems would also be P!
We all know the answer for this: either false or independent.
Conceptually the simplest mesons. All of them have neutral color charge:
- charged: down + anti-up or up + anti-down, therefore with net electrical charge electron charge
- neutral: down + anti-down or up + anti-up, therefore with net electrical charge 0
However, many, many, many terrible horrors come with it:
- it hasn't made the move to desktop for too many years. It could destroy Microsoft Windows and replace it with open source, but they just won't budge towards an unified mobile/desktop setup.
- vendors litter it with uninstallable bloatware that should be illegal. European Union to the rescue!!! www.cnbc.com/2020/12/15/digital-markets-act-eus-new-rules-on-big-tech.html
- vendors lock down devices so it is very hard to get sudo, let alone to modify their images!
- there isn't enough hardware standardization for open source distros to thrive like on desktop
- code drops mean that "master" is useless and trying to contribute from outside vendors' closed walls is a waste of time: stackoverflow.com/questions/1809774/how-to-compile-the-android-aosp-kernel-and-test-it-with-the-android-emulator/48310014#48310014
- if you ever go below the Java API, e.g. to C++ or AOSP build, everything is horrendous and undocumented
- Google doesn't care about the CLI, even the hello world requires creating infinite out-of-control boilerplate from a GUI: stackoverflow.com/questions/20801042/how-to-create-android-project-with-gradle-from-command-line/46994747#46994747
- the boot is uber bloated and takes forever in cycle simulators
- 1982 www.pnas.org/doi/pdf/10.1073/pnas.80.6.1579 DNA fragments differing by single base-pair substitutions are separated in denaturing gradient gels by Fischer and Lerman (1982). It is possible then.

- on smaller wavelengths, loss is due to Rayleigh scattering
- on longer wavelengths, loss is due to material absorption
