WebProkaryotes are small, single-celled living organisms. Since prokaryotic cells do not have a nucleus or organelles, gene expression happens out in the open cytoplasm, and all the stages can happen simultaneously. Controlling gene expression is … WebHence, within this mindset, the number of genes contained in a genome is estimated to be the genome size/1000. For bacterial genomes, this strategy works surprisingly well as can be seen in table 1 and Figure 1. For example, when applied to the E. coli K-12, genome of 4.6 x 10 6 bp, this rule of thumb leads to an estimate of 4600 genes, which ...
