Eventually, the join breaks, causing the seafloor to spring upwards several metres.
non-homologous end joining breaks.
The DNA repair mechanisms include homology-directed repair and non-homologous end joining breaks (Wyman and Kanaar 2006).
Importantly, NHEJ is mutagenic, since it joins broken ends with little or no homology, often resulting in small deletions and/or insertions surrounding the cleavage site [7].
By contrast, the untemplated NHEJ pathway is more error-prone as it rapidly processes and joins broken DNA ends (Lieber, 2010).
In human cells, most DSBs are repaired via a conserved pathway called non-homologous end joining (NHEJ), which is an error-prone pathway that readily joins broken DNA ends together independent of sequence context (Fig. 1; Lieber 2010).
The double-strand breaks (DSBs) of DNA consequently result in cellular DNA repair mechanisms, including homology-directed repair (HDR) and error-prone non-homologous end joining breaks (NHEJ), leading to gene modification at the target sites.
DSB repair through HR process is an error free pathway, since it requires an extensive region of sequence homology between the damaged and template strands, whereas NHEJ is an error prone alternate pathway for the repair of DSBs, which essentially joins broken chromosomal ends independent of sequence homology.
What you see in Egypt today are young people from across the political spectrum and classes who are willing to join forces, break ranks with their own parties and return to Tahrir Square to press for real freedom.
This change is traced easily, so the interfaces can for example join or break apart.
