Gene editing +

The CRISPR-Cas9 system has revolutionised gene-editing, but cutting DNA isn’t all it can do. From turning gene expression on and off to fluorescently tagging particular sequences, this animation explores some of the exciting possibilities of CRISPR.

Telomerase: a reverse transcriptase

Telomerase is a special reverse transcriptase that carries its own RNA template (ribonucleoprotein) and can elongate telomeres. It has a strong presence in frequently dividing cells (to prevent loss of function). It is not present in all cells. Telomerase activity is enhanced in cancer cells.
