The Ferrier Lecture is a Royal Society lectureship given every three years "on a subject related to the advancement of natural knowledge on the structure and function of the nervous system". [1] It was created in 1928 to honour the memory of Sir David Ferrier , a neurologist who was the first British scientist to electronically stimulate the ...
PCR inhibitors are any factor which prevent the amplification of nucleic acids through the polymerase chain reaction (PCR). [1] PCR inhibition is the most common cause of amplification failure when sufficient copies of DNA are present. [2] PCR inhibitors usually affect PCR through interaction with DNA or interference with the DNA polymerase.
Image illustrates DNA, RNA, and protein synthesis. The first two are nucleic acids. A nucleic acid inhibitor is a type of antibacterial that acts by inhibiting the production of nucleic acids. There are two major classes: DNA inhibitors and RNA inhibitors. [1] The antifungal flucytosine acts in a similar manner.
In his 50-year career, Ferrier published 180 papers, reviews and books, and gave 10 invited plenary lectures at international symposia. [15] His reviews were of particular benefit to the chemical community but perhaps of most value was the book "Monosaccharide Chemistry, [ 16 ] written with Dr Peter Collins in 1972 and majorly updated as ...
Sir David Ferrier FRS (13 January 1843 – 19 March 1928) was a pioneering Scottish neurologist and psychologist.Ferrier conducted experiments on the brains of animals such as monkeys and in 1881 became the first scientist to be prosecuted under the Cruelty to Animals Act, 1876 which had been enacted following a major public debate over vivisection.
DNA contains genes and provides the template to produce messenger RNA (mRNA). That mRNA is then translated into proteins. When a repressor protein binds to the silencer region of DNA, RNA polymerase is prevented from transcribing the DNA sequence into RNA. With transcription blocked, the translation of RNA into proteins is impossible.
Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells.
In molecular biology, endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain (namely DNA or RNA).Some, such as deoxyribonuclease I, cut DNA relatively nonspecifically (with regard to sequence), while many, typically called restriction endonucleases or restriction enzymes, cleave only at very specific nucleotide sequences.
