Time Alignment of Signals. I discussed the idea of a time-alignment scheme in the article Delays, Delays, Delays. The idea is that signals which have a mechanical delay of some kind (gas transport time, for example) can be time-aligned with signals that have a lesser or no such delay by means of a âlogicalâ delay line inserted into all channels.
Telomeres, dynamic structures capping the ends of chromosomes, are composed of long arrays of repeated deoxyribonucleic acid (DNA) sequences accompanied by closely associated proteins. In most organisms, these repeats are maintained by the enzyme, telomerase.
Telomerase is a crucial enzyme that controls and maintains telomeres. These are the tips of chromosomes that a) protect DNA from molecular attack and b) prevent strands of genetic material from sticking to each other. The enzyme is active in stem cells, germ cells, and tumour cells.
