The ligase chain reaction (LCR) is a method of DNA amplification. The ligase chain reaction (LCR) is an amplification process that differs from polymerase chain reaction (PCR) in that it involves a thermostable ligase to join two probes or other molecules together which can then be amplified by standard PCR cycling.

In enzymology, a leucoanthocyanidin reductase (EC 1.17.1.3) (LAR, aka leucocyanidin reductase or LCR) is an enzyme that catalyzes the chemical reaction (2R,3S)-catechin + NADP + + H 2 O ⇌ {\displaystyle \rightleftharpoons } 2,3-trans-3,4-cis-leucocyanidin + NADPH + H +
The laminar finite rate model computes the chemical source terms using the Arrhenius expressions and ignores turbulence fluctuations. This model provides with the exact solution for laminar flames but gives inaccurate solution for turbulent flames, in which turbulence highly affects the chemistry reaction rates, due to highly non-linear Arrhenius chemical kinetics.
This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
A locus control region (LCR) is a long-range cis-regulatory element that enhances expression of linked genes at distal chromatin sites. It functions in a copy number-dependent manner and is tissue-specific, as seen in the selective expression of β-globin genes in erythroid cells . [ 1 ]
In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only.

The profile of the curve is determined by the c-value, which is calculated using the equation: c = n K a M {\displaystyle c=nK_{a}M} where n {\displaystyle n} is the stoichiometry of the binding, K a {\displaystyle K_{a}} is the association constant and M {\displaystyle M} is the concentration of the molecule in the cell.
The cation transport number of the leading solution is then calculated as t + = z + c L A F I Δ t {\displaystyle t_{+}={\frac {z_{+}cLAF}{I\Delta t}}} where z + {\displaystyle z_{+}} is the cation charge, c the concentration, L the distance moved by the boundary in time Δ t , A the cross-sectional area, F the Faraday constant , and I the ...
