Figure 13: Correlation of order-specific SINEs and LINEs in human and mouse orthologous regions.
From: Initial sequencing and comparative analysis of the mouse genome
SINE and LINE densities were calculated for 4,126 orthologous pairs with a constant size of 500 kb in mouse. a, b, Strong linear correlation of Alu density in human, and both the Alu-like B1 SINEs (a) and the unrelated B2 SINEs (b) densities in mouse. These correlations are stronger than the correlation of SINE density with (G+C) level (c). d, The relationship of LINE1 density in human and mouse orthologous regions is not linear, reflecting the more extreme bias of LINE1 for (A+T)-rich DNA in mouse.
