Hyder, Avery, MacLeod and McCarty used strands of purified DNA such as this, precipitated from solutions of cell components, to perform bacterial transformations. The Avery–MacLeod–McCarty experiment was an experimental demonstration by Oswald Avery, Colin MacLeod, and Maclyn McCarty that, in 1944, reported that DNA is the substance that causes bacterial transformation, in an era when it ...
This technique is one of the principal tools of molecular biology. The basic principle is that DNA fragments can be separated by applying an electric current across the gel - because the DNA backbone contains negatively charged phosphate groups, the DNA will migrate through the agarose gel towards the positive end of the current.

Cryptic crossword clues consist typically of a definition and some type of word play. Cryptic crossword clues need to be viewed two ways. One is a surface reading and one a hidden meaning. [27] The surface reading is the basic reading of the clue to look for key words and how those words are constructed in the clue. The second way is the hidden ...
M phase See mitosis. macromolecule Any very large molecule composed of dozens, hundreds, or thousands of covalently bonded atoms, especially one with biological significance. . Many important biomolecules, such as nucleic acids and proteins, are polymers consisting of a repeated series of smaller monomers; others such as lipids and carbohydrates may not be polymeric but are nevertheless large ...
Molecular medicine is a new scientific discipline in European universities. [11] Combining contemporary medical studies with the field of biochemistry , it offers a bridge between the two subjects. At present only a handful of universities offer the course to undergraduates .
Molecular binding occurs in biological complexes (e.g., between pairs or sets of proteins, or between a protein and a small molecule ligand it binds) and also in abiologic chemical systems, e.g. as in cases of coordination polymers and coordination networks such as metal-organic frameworks.
