About the really tiny stuff…
 On the “quantum level” a peculiar dualistic nature has
been observed: curiously, “quantum size” stuff appears
  to be both particles and waves, at the same time!
The following few slides are misleading: Atoms, and
what they’re made of, are not “things” in any ordinary
sense. An electron, for example, is not a little sphere
orbiting a nucleus, but rather “something, vibrating in
nothing”: like a “misty cloud,” it is “smeared out” as a
standing wave—and the particle aspect of this wave
     may be located anywhere within the “cloud.”
 Note also that so far, this is theory only: Nobody has
  ever directly “seen” anything as small as an atom.

                      1) Triplets 10, 11, & 14 serve only as stop codes (no amino acid encodings) 2) Triplets 15 & 35 encode amino acids W and M, respectively

                      3) Triplet 35 does “double duty” as the universal “start transcription" code 4) Amino acid names shown in their standard 3- and 1-letter codes

                                              Note also that the sum of triplet values 10+11+14 (the stop codes) equals 35 (the start code)!

Relaxed muscle myosin cannot bind to actin, as the binding
sites are blocked—by protein tropomysin—and must first be
unblocked (accomplished by the regulator protein troponin).
Signal receptor molecules open Ca+ ion channels, resulting in
troponin release, which exposes the actin binding sites.
Myosin now binds to actin, and the myosin head bends (by
“spending” ATP ), and the attached actin filament slides along!
Relax signals close the Ca+ ion channels, resulting in removal
of troponin, allowing tropomysin to reblock the actin binding
sites. The myosin heads retract, and the cycle may repeat.

  • 10. About the really tiny stuff… On the “quantum level” a peculiar dualistic nature has been observed: curiously, “quantum size” stuff appears to be both particles and waves, at the same time! The following few slides are misleading: Atoms, and what they’re made of, are not “things” in any ordinary sense. An electron, for example, is not a little sphere orbiting a nucleus, but rather “something, vibrating in nothing”: like a “misty cloud,” it is “smeared out” as a standing wave—and the particle aspect of this wave may be located anywhere within the “cloud.” Note also that so far, this is theory only: Nobody has ever directly “seen” anything as small as an atom.

  • 41. ADP Muscle Cell Power Cycle ADP Pi Pi ATP ATP HOH HOH Relaxed muscle myosin cannot bind to actin, as the binding sites are blocked—by protein tropomysin—and must first be unblocked (accomplished by the regulator protein troponin). Signal receptor molecules open Ca+ ion channels, resulting in troponin release, which exposes the actin binding sites. Myosin now binds to actin, and the myosin head bends (by “spending” ATP ), and the attached actin filament slides along! Relax signals close the Ca+ ion channels, resulting in removal of troponin, allowing tropomysin to reblock the actin binding sites. The myosin heads retract, and the cycle may repeat. Bi-polar thick Myosin filament (in muscle cell Sarcomere) Actin filaments attached to and pulled back by very strong titin protein “springs”
