Document Summary
Have many copies of the same regulatory elements = polyploid. Encode project: q: what proportion of the non-coding dna in the genome is functional?? (some could just be junk dna, some are useful, a: encode project. Note: not every cell in every tissue will have 75% that is transcribed, this statistic is different between every cell type. & tissue type, 75% is only a general trend across human genomes: 80% of the human genome is associated with at least one biochemical function, 20% have no functions (junk dna) At rst, encodes stated that 80% of the human genome are functional . Combined with the previous statistic, implies that: 80% functional sequences = 75% transcribed rnas + 5% regulatory / gene expression + protein coding ; 20% non-functional sequences. Prior to this: scientists considered that the majority of the genome contained junk dna.
