... clones containing the ATTS0477 sequence, and ATTS0477-1ike sequences. We wished to identify the latter clones because many disease-resistance genes are members of clustered multi-gene families (Martin et al., 1993; Song et al., 1995), and we wished to determine if ATTS0477 was similar in this regard ...

Contour length analysis showed that the DNA is still wrapped around the UvrB protein in these preincision complexes as long as UvrB has bound ATP (Verhoeven et al., 2001). The calculated size of a potential UvrB dimer (152 kDa) is almost exactly the size of th ...

DNA damage theory of aging

The DNA damage theory of aging proposes that aging is a consequence of unrepaired accumulation of naturally occurring DNA damages. Damage in this context is a DNA alteration that has an abnormal structure. Although both mitochondrial and nuclear DNA damage can contribute to aging, nuclear DNA is the main subject of this analysis. Nuclear DNA damage can contribute to aging either indirectly (by increasing apoptosis or cellular senescence) or directly (by increasing cell dysfunction).In humans and other mammals, DNA damage occurs frequently and DNA repair processes have evolved to compensate. In estimates made for mice, on average approximately 1,500 to 7,000 DNA lesions occur per hour in each mouse cell, or about 36,000 to 160,000 per cell per day. In any cell some DNA damage may remain despite the action of repair processes. The accumulation of unrepaired DNA damage is more prevalent in certain types of cells, particularly in non-replicating or slowly replicating cells, such as cells in the brain, skeletal and cardiac muscle.
