  2. Denaturation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Denaturation_(biochemistry)

    In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat. [3]

  3. Deamination - Wikipedia

    en.wikipedia.org/wiki/Deamination

    Enzymes that catalyse this reaction are called deaminases. In the human body, deamination takes place primarily in the liver; however, it can also occur in the kidney. In situations of excess protein intake, deamination is used to break down amino acids for energy. The amino group is removed from the amino acid and converted to ammonia.

  4. Restriction map - Wikipedia

    en.wikipedia.org/wiki/Restriction_map

    A restriction map is a map of known restriction sites within a sequence of DNA.Restriction mapping requires the use of restriction enzymes.In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA.

  5. Hyperchromicity - Wikipedia

    en.wikipedia.org/wiki/Hyperchromicity

    The hyperchromic effect is the striking increase in absorbance of DNA upon denaturation. The two strands of DNA are bound together mainly by the stacking interactions, hydrogen bonds and hydrophobic effect between the complementary bases. The hydrogen bond limits the resonance of the aromatic ring so the absorbance of the sample is limited as well.

  6. Equilibrium unfolding - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_unfolding

    In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.

  7. Helicase-dependent amplification - Wikipedia

    en.wikipedia.org/wiki/Helicase-dependent...

    The polymerase chain reaction is the most widely used method for in vitro DNA amplification for purposes of molecular biology and biomedical research. [1] This process involves the separation of the double-stranded DNA in high heat into single strands (the denaturation step, typically achieved at 95–97 °C), annealing of the primers to the single stranded DNA (the annealing step) and copying ...

  8. Non-competitive inhibition - Wikipedia

    en.wikipedia.org/wiki/Non-competitive_inhibition

    Non-competitive inhibition is a type of enzyme inhibition where the inhibitor reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate. [1] This is unlike competitive inhibition, where binding affinity for the substrate in the enzyme is decreased in the presence of an inhibitor.

  9. Immobilized enzyme - Wikipedia

    en.wikipedia.org/wiki/Immobilized_enzyme

    Since the enzyme in this process does not interact chemically with the polymer/ material of the support fibers/lattice, it remains protected from denaturation with time. [6] Basically, the enzyme is trapped in insoluble beads or microspheres, such as calcium alginate beads. However, these insoluble substances hinder the arrival of the substrate ...
