摘要: Regions of the genome not coding for proteins or involved in cis-acting regulatory activities are frequently viewed as lacking functional value. However, a number recent large-scale studies have revealed significant regulated transcription unannotated portions variety plant and animal genomes, allowing new appreciation widespread large genome. High-resolution mapping sites human fly genomes has provided an alternative picture extent organization offered insights biological functions some newly identified transcripts. Considerable observed developmental cell-type-specific parts protein-coding transcripts, often serving novel, 5' transcriptional start sites. These distal situated at distances from annotated gene alternatively join with ignore other intervening genes to comprise novel data support interlaced model which many regions serve multifunctional purposes highly modular their utilization. This illustrates underappreciated organizational complexity one roles
