First, Sir2 suppresses recombination at the repetitive array encoding the ribosomal rRNA (the rDNA locus) [ 5].
According to the genome annotation, the histone gene complex of D. melanogaster is composed of 23 canonical histone gene repeat units (His-GUs), each bearing a gene array encoding the five canonical histones (for simplicity we refer to them as 'histones'; for details of the histone complex see http://flybase.org; Fig 1A).
When an animal rotates with constant angular velocity through the environment, the spatiotemporal response profile of the photoreceptor array encodes the velocity of self-motion through the slope of oriented streaks in space-time (front face, Appendix figure 1B) (Adelson and Bergen, 1985).
Nonetheless, the normalized ratios for the ~18,000 genes on the array were tightly clustered around unity (~1), as expected, but the cDNA on the array encoding HPS displayed exceptional hybridization ratios in these experiments in every case.
Moreover, the 1T-1R cell array encoded letters based on the standard ASCII character code.
The array encoded an endogenous protein, SUR-5, fused to the reporter protein, GFP, driven by the sur-5 promoter (sur-5::gfp).
Another glutathione reductase gene (At2g24170), which however, was not present in our cDNA array, encodes a cytoplasmic protein, and this protein showed increased amounts both under Cold/Light and Cold/Dark conditions.
They then used the array to encode the I.B.M. motto "Think" by repeatedly programming the memory block to store representations of its five letters.
The separation of parasitic elements from cooperators would be cemented by the emergence of physical linkage of the latter: genes that encode components of the replication machinery and are physically linked to genes for accessory functions would be locked into ensembles of cooperators, whereas solitary genes (or small gene arrays) encoding replication functions would occupy the parasitic niche.
Unlike prevalent types of video information encoding (for instance, differential encoding, code-pulse encoding, and delta modulation), which are based on the sequential encoding of difference information, an approach suggested here processes the results of the data array encoding distributed in the space-time domain.
There are notable exceptions to this pattern of gene regulation in that some gene arrays that encode the parasite's variant surface glycoproteins (VSGs) and procyclin expressions sites in bloodstream forms and procyclic forms, respectively, are co-regulated and co-transcribed by RNA polymerase I[ 32].
