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.
A chromosome is a long strand of DNA. At the end of a chromosome is a telomere, which acts like a bookend. Telomeres keep chromosomes protected and prevent them from fusing into rings or binding with other DNA. Telomeres play an important role in cell division. Each time a cell divides, the DNA unwraps and the information in the DNA is copied.
