Thus, in her experiments, McClintock observed several fundamental properties of chromosome biology ... the experiments that revealed the actual structure of telomeres. Nature provided the model ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

These motors play distinct roles in manipulating chromosome structure. Swimming motors, similar to RNA polymerases -; enzymes that copy DNA sequences into RNA -; help expand and contract the ...

Experiments show that CENP-B works as a dimer, so it may be able to cross-link two nearby satellite sequences, thereby contributing to the higher-order structure of the chromosome. Figure 3 shows ...
