nucleoprotein filament造句

• The BCDX2 complex appears to act by facilitating the assembly or stability of the RAD51 nucleoprotein filament.
• The resulting RecA-coated nucleoprotein filament then searches out similar sequences of DNA on a homologous chromosome.
• Step 6 : RecBCD unbinds from the DNA duplex, leaving a RecA nucleoprotein filament on the 3'tail.
• Unlike other proteins involved in DNA metabolism, the RecA / Rad51 family forms a helical nucleoprotein filament on DNA.
• Upon finding such a sequence, the single-stranded nucleoprotein filament moves into the homologous recipient DNA duplex in a process called " strand invasion ".
• BRCA2 also redirects RAD51 from dsDNA and prevents dissociation from ssDNA . The BCDX2 complex appears to act by facilitating the assembly or stability of the RAD51 nucleoprotein filament.
• Pol V directly interacts with RecA * at the 3'tip of the nucleoprotein filament; this is the site of the nascent DNA strand where Pol V restarts DNA synthesis.
• Like its role in DNA replication, this keeps ssDNA from binding to itself ( self-complementizing ) so that the resulting nucleoprotein filament can then be bound by Rad51 and its cofactors.
• These overhangs are then bound to form a nucleoprotein filament, which can then locate DNA sequences similar to one of the 3 overhangs, initiating a single-stranded strand invasion into the DNA duplex containing these sequences.
