Figure 4From: Large scale analysis of positional effects of single-base mismatches on microarray gene expression data Mean level of log 2 (PM/MM i ) for 3 groups of mismatch positions for each mismatch type. The x-axis denotes the 12 mismatch types. The first nucleotide represents the rhesus probe (PM) and the second nucletotide represents the human probe (MM).Back to article page
