Web18 apr. 2016 · This one is actually pretty easy - it's homotopic to a wedge of n +1 n + 1 circles! It helps to begin by drawing the torus as a CW-complex, i.e. a rectangle with opposite edges identified. In the case when n = 1 n = 1, our space looks like a rectangle with a disc removed. http://www.math.sci.hiroshima-u.ac.jp/hmj/v36.1/141-170.pdf

DSBs are repaired by endogeneous cellular routes such as non-homologous end participation (NHEJ) and homology-directed repair (HDR). Providing an exogenous DNA template during repair allows for this intentional, precise …

WebChapter 0 Exercise 16 We think Sn as the one point compactification of Rn.From this point of view, the inclusion Sn ⊂ S n+1is just the inclusion of Rn ∪{∞} inside R ∪{∞} given by the hyperplane x n+1 = 0 (and that identifies the points at infinity). Therefore S∞ = ∪ nS n is homeomorphic to R∞ ∪{∞}, where R∞ is the union ∪ nR n equipped with the weak topology.
