Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity (normal molecule, reaction intermediate, etc.) into two or more fragments. [1] Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis. In short, the chemical reaction in which two or more ...
The term modifications in genetics refers to both naturally occurring and engineered changes in DNA. Incidental, or natural mutations occur through errors during replication and repair, either spontaneously or due to environmental stressors. Intentional modifications are done in a laboratory for various purposes, developing hardier seeds and ...
Chemical reaction. A thermite reaction using iron (III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake. A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [ 1] When chemical reactions occur, the atoms are rearranged and the reaction ...
Subjects. Six students, ranging between 6 and 15 years old were interviewed, to test both the misconceptions themselves, and whether they changed with the age of the students (Table 2). The students could be roughly split into three age groups: a) 6 to 7 years old, b) 10 years old and c) 14 to 15 years old. Table 2.
Le Chatelier's principle (pronounced UK: / lə ʃæˈtɛljeɪ / or US: / ˈʃɑːtəljeɪ / ), also called Chatelier's principle (or the Equilibrium Law ), [1] [2] is a principle of chemistry used to predict the effect of a change in conditions on chemical equilibrium. [3] The principle is named after French chemist Henry Louis Le Chatelier ...
Redox (/ ˈ r ɛ d ɒ k s / RED-oks, / ˈ r iː d ɒ k s / REE-doks, reduction–oxidation [2] or oxidation–reduction [3]: 150 ) is a type of chemical reaction in which the oxidation states of the reactants change. [4] Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a ...
CRISPR gene editing. CRISPR-Cas9. CRISPR gene editing (CRISPR, pronounced / ˈkrɪspər / "crisper", refers to " c lustered r egularly i nterspaced s hort p alindromic r epeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial ...
Substrate (chemistry) In chemistry, the term substrate is highly context-dependent. [1] Broadly speaking, it can refer either to a chemical species being observed in a chemical reaction, or to a surface on which other chemical reactions or microscopy are performed. In the former sense, a reagent is added to the substrate to generate a product ...
