DNA Molecule

Some articles on dna molecule, dna, molecules:

P1 Phage - Genome
... is in the form of a linear double stranded DNA molecule ... In the viral particle the DNA molecule is longer (110Kbp) than the actual length of the genome ... It is created by cutting an appropriately sized fragment from a concatemeric DNA chain having multiple copies of the genome ...
Homologous Recombination
... are exchanged between two similar or identical molecules of DNA ... most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks ... Homologous recombination also produces new combinations of DNA sequences during meiosis, the process by which eukaryotes make gamete cells, like sperm and egg ...
Sticky And Blunt Ends - Variations in Double-stranded Molecules - Overhangs and Sticky Ends
... An overhang is a stretch of unpaired nucleotides in the end of a DNA molecule ... This is most often adenosine and is created as a 3' overhang by some DNA polymerases ... The product is joined with a linear DNA molecule with 3' thymine overhangs ...
In Vitro Compartmentalization - Method - Breaking Emulsion and Coupling of Genotype and Phenotype
... to the encoding gene as they become free floating in a heterogeneous population of molecules ... The first method is to attach each DNA molecule with a biotin group and an additional coding sequence for streptavidin (STABLE display) ... All the newly formed proteins/peptides will be in fusion with streptavidin molecules and bind to their biotinylated coding sequence ...
Magnetic Tweezers - Typical Experimental Set-up
... A double-stranded DNA molecule is fixed with multiple binding sites on one end to a glass surface and on the other to a magnetic micro bead, which can be ... By turning the magnets, torsional stress can be applied to the DNA molecule ... Rotations in the sense of the DNA helix are counted positively and vice versa ...

Famous quotes containing the words molecule and/or dna:

    We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.
    Cyril Ponnamperuma (b. 1923)

    Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.
    William Gibson (b. 1948)
