The proportion of non-repetitive DNA is calculated by using the length of non-repetitive DNA divided by <answer>genome size</answer>. Protein-coding genes and RNA-coding genes are generally non-repetitive DNA. A bigger genome does not mean more genes, and the proportion of non-repetitive DNA decreases along with increasing <answer>genome size</answer> in higher eukaryotes.
What is the size of non-repetitive DNA divided by to get the proportion of non-repetitive DNA?
genome size
