DNA polymerases

Subject Area - Biochemistry, Genetic Engineering The enzyme DNA polymerase catalyzes the synthesis of DNA polynucleotides by adding nucleoside phosphates to a strand of DNA. Substrates are the four different 2'-deoxyribonucleotides dATP, dGTP, dCTP and dTTP, with each extension step forming a new phosphodiester bond and releasing pyrophosphate.

Lewis theory

US chemist Gilbert Newton Lewis developed an acid-base theory related to the electron pair. Lewis acid - is the chemical species that receives the electron pair in a chemical reaction. Lewis base - is the chemical species that donates the electron pair in a chemical reaction. Example: Summary table of acid-base theories BASIC ACID THEORY Arrhenius Libera H + in aqueous solution Libera OH- in aqueous solution Bronsted-Lowry Donate 1 proton Receive 1 proton Lewis Receive electron pair Donate electron pair

Practical course 3: DNA hybridization

Introduction: DNA hybridization Hybridization is a molecular biological technique in which labeled primers or another single-stranded DNA are attached to a single-stranded nucleic acid. This method is used to detect certain nucleic acids in a mixture or to determine the sequence similarity of two nucleic acids on the basis of the melting temperature.

Reflectometric interference spectroscopy

Reflektometrische Interferenzspektroskopie (RIfS)Weißlichtinterferometrie an Schichtsystemen erlaubt es, ein einfaches und robustes optisches Sensorsystem aufzubauen. Für jedeeingestrahlte Wellenlänge kommt es zu Überlagerungen der an den beiden Phasengrenzen einer Schicht reflektierten Teilwellen inAbhängigkeit vom Einfallswinkel, dem Brechungsindex n und von der Schichtdicke d.
