Figure 12From: Expansion of a novel endogenous retrovirus throughout the pericentromeres of modern humansEvolution of K222 in human chromosomes. (A) Phylogenetic neighbor-joining tree of K222 integration sequences amplified from the single human chromosomes grown in human/rodent cell hybrids. The tree was constructed in the same way as was the tree in Figure 9. (B) Nucleotide sequence alignment of K222 insertion sequences amplified from single human chromosomes. The sequences are compared to the K222 insertion sequence amplified from the genome of the H9 cell line. Dots indicate nucleotide similarities to the H9 sequence. Nucleotide substitutions and insertions are indicated in letters.Back to article page
