Telomere length is tightly controlled in normal cellular function and the human population. Here, the authors reveal that telomere synthesis is bidirectionally constrained by cellular nucleotide pools, in a manner which may be therapeutically manipulated.

The combination of dynamic, energy-driven folding and growth with structural stiffness and length control is difficult to achieve in synthetic polymer self-assembly. Here we show that highly charged, monodisperse DNA-oligomers assemble via seeded growth into length-controlled supramolecular fibers during ...
51 Looping out one or several repeats in the newly synthesized DNA strand should convert the loop into expansions after a second round of replication. However, this simple idea fails to explain why only a handful of all repeats expand and what determines the threshold length and the large-...
较早的DNA检测依赖的是RFLP(Restriction fragment length polymorphism),即“限制性内切片段长度多态性”,原理是,不同序列的DNA经限制性内切酶切割后会产生长度不同的片段。而现行应用最广泛的是PCR检测,它主要通过扩增短的串联重复序列(short tandem repeats,STR)长度差异来鉴定亲子关系。爱好刑侦的童鞋都知道,当代法...
