WebSummary. Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5’) of the sense or coding strand of the transcribed gene. The coding strand is the DNA strand that encodes codons and whose sequence corresponds to the mRNA transcript produced. The antisense strand is referred to as the template strand or non ... WebThe density of DNA is determined by its base composition, with AT-rich sequences being less dense than GC-rich sequences. ... For example, the genome of E. coli is approximately 4.6 × 10 6 base pairs long and … WebJan 15, 2003 · Human genes are commonly around 27,000 base pairs long, and some are up to 2 million base pairs. Very simple organisms tend to have relatively small genomes. The smallest genomes, belonging to primitive, single-celled organisms, contain just over half a million base pairs of DNA. list of government hospitals in western cape
