Figure 2. Comparison between the overall mRNA decay rates and the poly(+) mRNA decay rates.

(A) Distribution of half-lives of mRNA overall decay (blue) and polyA(+) mRNA decay (red).

(B) Scatter plot of half-lives of mRNA overall decay and polyA(+) mRNA decay for the 4661 mRNAs. Cor.Coeff. = 0.50. The purple dashed line indicates a slope of 1. The green solid line is the best least-squares linear fit of the data, with a slope of 0.41 and y intercept of 1 min (in log scale).
