WebChromosomes condense and centrosomes move to the opposite sides of the cell. Metaphase 2: The centrosomes have two kinetochores that attach to spindle fibres from the centrosomes at opposite ends of the cell. Anaphase 2: Here, the spindle fibres contract and separate from non-sister chromatids. WebApr 9, 2024 · To begin DNA replication, unwinding enzymes called DNA helicases cause short segments of the two parent DNA strands to unwind and separate from one another at the origin of replication to form two "Y"-shaped replication forks. These replication forks are the actual site of DNA copying (Figure 19.4. 1 ).
WebReplication always starts at specific locations on the DNA, which are called origins of replication and are recognized by their sequence. E. coli, like most bacteria, has a single origin of replication on its chromosome.
