Source: WordNetAlthough co-expression does not necessarily indicate co-regulation, methylation of bidirectional promoter regions has been shown to downregulate both genes, and demethylation to upregulate both genes. citation There are exceptions to this, however. Source: Internet
Both were TTL compatible, had an 8-bit bidirectional data bus, a 16-bit stack pointer, a 16-bit address bus that could address 64 KB of memory, and came in a 40-pin DIP package. Source: Internet
Forty-five percent of human somatic oncogenes seem to be regulated by bidirectional promoters - significantly more than non-cancer causing genes. Source: Internet
For example, the Kam language has 9 tones: 3 more-or-less fixed tones (high, mid and low); 4 unidirectional tones (high and low rising, high and low falling); and 2 bidirectional tones (dipping and peaking). Source: Internet
As FPGA designs employ very fast I/Os and bidirectional data buses, it becomes a challenge to verify correct timing of valid data within setup time and hold time. Source: Internet
Converters also exist that connect PS/2 keyboards and mice (usually one of each) to a USB port. citation These devices present two HID endpoints to the system and use a microcontroller to perform bidirectional data translation between the two standards. Source: Internet
