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.
Telomeres are appended to the ends of all 46 chromosomes in all of our cells. Once telomeres become too short, cells can no longer multiply to replenish body tissues. The progressive shortening of this chromosome-capping, protective bit of DNA now appears to be associated with risk for certain chronic diseases.
