ps:

In the end, the lagging strand (which is longer) forms a T-loop, showing that the chromosome is finished.

This serves as a protection against losing information, prevents chromosomes to bind to each other and so on.

The thing to remember is that telomerase is very often inactive on somatic cells,

which means that those chromosomes shorten every time they replicate. This is why we die of age.

你還有再用喔..
