Figure 1From: The mammalian transcriptome and the function of non-coding DNA sequencesRatios of the protein-coding, non-coding, and untranscribed sequences in bacterial, yeast, nematode and mammalian genomes. Estimations of the transcribed and protein-coding parts of genomes are based on the sequence length of annotated genes [3, 12, 13, 73]. Estimation of the transcribed portion of the human genome is based on the sequence length occupied by the annotated genes on chromosomes 6, 7, 14, 20, and 22 [5].Back to article page
