replicative transposition

(noun)

A mechanism of transposition in which the transposable element is duplicated during the reaction, so that the transposing entity is a copy of the original element.

Examples of replicative transposition in the following topics:

  • Mu: A Double-Stranded Transposable DNA Bacteriophage

    • It can then use transposition to initiate its viral DNA replication.
    • The mechanism of transposition can be either "copy and paste" or "cut and paste. " Transposition can create phenotypically significant mutations and alter the cell's genome size.
    • Mu phage transposition is the best known example of replicative transposition.
    • Replicative transposition is a mechanism of transposition in molecular biology, proposed by James A.
    • In this mechanism, the donor and receptor DNA sequences form a characteristic intermediate "theta" configuration, sometimes called a "Shapiro intermediate. " Replicative transposition is characteristic to retrotransposons and occurs from time to time in class II transposons.

  • Inactivating and Marking Target Genes with Transposons

    • The mechanism of transposition can be either "copy and paste" or "cut and paste. " Transposition can create phenotypically significant mutations and alter the cell's genome size.
    • Transposons in bacteria usually carry an additional gene for function other than transposition---often for antibiotic resistance.
    • Transposons are semi-parasitic DNA sequences that can replicate and spread through the host's genome.
    • Transposition is a precise process in which a defined DNA segment is excised from one DNA molecule and moved to another site in the same or different DNA molecule or genome.

  • Transposition

    • In post-tonal music, transposition is often associated with motion: Take a chord, motive, melody, and when it is transposed, the aural effect is of moving that chord, motive, or melody in some direction.
    • Transposition is an operation—something that is done to a pitch, pitch class, or collection of these things—or alternatively a measurement—representing the distance between things.
    • Given the collection of pitch classes in m. 1 above and transposition by T4:
    • Alternatively, to determine the transpositional relationship between two things, subtract the first thing from the second.

  • Common Tones under Transposition

    • Any other transposition will have zero common tones.
    • If an interval class vector has a tritone, it will retain twice as many common tones under tritone transposition than is indicated in the vector.

  • Avoiding Transposition

    • In some situations, you can avoid transposition, or at least avoid doing the work yourself.

  • How to Transpose Music

    • The transposition you choose will depend on why you are transposing.
    • If you already know what transposition you need, you can go to step two.
    • If you have chosen the transposition because you want a particular key, then you should already know what key signature to use.
    • (If you don't, see Key Signature. ) If you have chosen the transposition because you wanted a particular interval (say, a whole step lower or a perfect fifth higher), then the key changes by the same interval.
    • This step is very important; if you use the wrong key signature, the transposition will not work.

  • Analyzing Atonal Music

    • Pentatonic – The black key collection and all of its transpositions, prime form: (02479).
    • Pitch transposition involves moving every pitch in a collection up or down by a specified interval.
    • Pitch-class transposition does the same thing.
    • Transposition operations can be denoted by a capital "T" followed by a subscript indicating the number of semitones of the transposition.
    • For pitch-class transpositions, use ordered pitch-class intervals (numbers 0–11).

  • DNA Replication in Eukaryotes

    • There are specific chromosomal locations called origins of replication where replication begins.
    • Because two helicases bind, two replication forks are formed at the origin of replication; these are extended in both directions as replication proceeds creating a replication bubble.
    • Eukaryotic chromosomes have multiple origins of replication, which initiate replication almost simultaneously.
    • Each origin of replication forms a bubble of duplicated DNA on either side of the origin of replication.
    • Once all the template nucleotides have been replicated, the replication process is not yet over.

  • DNA Replication in Prokaryotes

    • There are specific nucleotide sequences called origins of replication where replication begins.
    • Two replication forks at the origin of replication are extended bi-directionally as replication proceeds.
    • A primer provides the free 3'-OH end to start replication.
    • The replication fork moves at the rate of 1000 nucleotides per second.
    • A replication fork is formed when helicase separates the DNA strands at the origin of replication.

  • Inversion

    • Inversion, like transposition, is often associated with motion that connects similar objects.
    • Unlike transposition, however, the interval content of these two gestures is not arranged in the same way.
