Asymmetry in the synthesis of leading and lagging strands. S phase (Synthesis phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. [1] Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely ...
"Direct" CP violation is allowed in the Standard Model if a complex phase appears in the Cabibbo–Kobayashi–Maskawa matrix (CKM matrix) describing quark mixing, or the Pontecorvo–Maki–Nakagawa–Sakata matrix (PMNS matrix) describing neutrino mixing. A necessary condition for the appearance of the complex phase is the presence of at ...
Patterson function – a function used to solve the phase problem in X-ray crystallography; Periodic table (crystal structure) – (for elements that are solid at standard temperature and pressure) gives the crystalline structure of the most thermodynamically stable form(s) in those conditions. In all other cases the structure given is for the ...
Of the four DNA damage checkpoints, two have an additional process for monitoring DNA damage other than activating p53. Before entry into S phase and during S phase, ATM/R also activates Chk1/2 that inhibits Cdc25A, a protein responsible for activating cyclin-Cdk dimers. Without cyclin dimer activation, the cell cannot transition through the cycle.
Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). [1] Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. [ 2 ]
Charge conjugation occurs as a symmetry in three different but closely related settings: a symmetry of the (classical, non-quantized) solutions of several notable differential equations, including the Klein–Gordon equation and the Dirac equation, a symmetry of the corresponding quantum fields, and in a general setting, a symmetry in (pseudo-)Riemannian geometry.
Loschmidt's paradox is equivalent to the question of how it is possible that there could be a thermodynamic arrow of time given time-symmetric fundamental laws, since time-symmetry implies that for any process compatible with these fundamental laws, a reversed version that looked exactly like a film of the first process played backwards would ...
