  2. Minichromosome - Wikipedia

    en.wikipedia.org/wiki/Minichromosome

    Minichromosomes can be either linear or circular pieces of DNA. [3] By minimizing the amount of unnecessary genetic information on the chromosome and including the basic components necessary for DNA replication (centromere, telomeres, and replication sequences), molecular biologists aim to construct a chromosomal platform which can be utilized to insert or present new genes into a host cell.

  3. Minichromosome maintenance - Wikipedia

    en.wikipedia.org/wiki/Minichromosome_Maintenance

    MCM2-7 is required for both DNA replication initiation and elongation; its regulation at each stage is a central feature of eukaryotic DNA replication. [3] During G1 phase, the two head-to-head Mcm2-7 rings serve as the scaffold for the assembly of the bidirectional replication initiation complexes at the replication origin.

    en.wikipedia.org/wiki/Biomolecular_structure

    Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.The structure of these molecules may be considered at any of several length scales ranging from the level of individual atoms to the relationships among entire protein subunits.

  6. Synthetic biological circuit - Wikipedia

    en.wikipedia.org/wiki/Synthetic_biological_circuit

    Engineered systems are the result of implementation of combinations of different control mechanisms. A limited counting mechanism was implemented by a pulse-controlled gene cascade [ 19 ] and application of logic elements enables genetic "programming" of cells as in the research of Tabor et al., which synthesized a photosensitive bacterial edge ...

    Image of chicken chromosomes featuring the many microchromosomes (appearing as dots). The arrows indicate a stained gene locus on homologous macrochromosomes.. A microchromosome is a chromosome defined for its relatively small size.

    The Flip-FRT system operates in a similar way, with the Flip recombinase recognizing FRT sequences. By crossing an organism containing the recombinase sites flanking the gene of interest with an organism that expresses the SSR under control of tissue specific promoters, it is possible to knock out or switch on genes only in certain cells. This ...

  9. Chimeric nuclease - Wikipedia

    en.wikipedia.org/wiki/Chimeric_nuclease

    The nuclease domain is responsible for physical cleavage of DNA strands and may introduce either single stranded or double-stranded breaks. FokI is an example of a sequence-specific endonuclease whose non-specific nuclease domain introduces double stranded breaks and has been used in a variety of experiments including identification of high- and low-affinity binding sites of transcription ...
