  1. ...of individual nucleotides. In this study, we examine the problem of detecting nonneutral substitution rates from aligned genomic sequences, focusing on what is possible with currently available data for the eutherian mammals. Our contributions consist of four main components: (1) a detailed comparison of four...
  2. ...Sequencing Consortium 2002 ) provide an opportunity to better understand rates and mechanisms of eutherian evolution. Previous analysis of whole- alignments between human and mouse showed that the rates of several processes by which DNA diverges, including neutral nucleotide substitution, insertions...
  3. ...insights into the factors that covary with, and therefore may be affecting or affected by, recombination that are seen in only one species. Data from more mammals will likely reveal lineage-specific patterns in the evolution of recombination. Genetic maps are available for a number of additional species...
  4. ...of recombination-driven deletion in driving TE distributions over evolutionary time. Thus, Alu and L1 densities have been influenced by the combination of distinct local landscapes and the unique evolutionary dynamics of sex chromosomes. [Supplemental material is available online at http://www..org.] Transposable...
  5. ...for the accumulation of deleterious substitutions to be apparent in increased d N /d S values. We present evidence in a separate manuscript that, indeed, recombination rates are an ancestral trait of metatherian and eutherian mammals (C. Webber and C.P. Ponting, in prep.). A model of inefficient purifying selection...

Enhancement of reporter gene de novo methylation by DNA fragments from the α-fetoprotein control region. J. Biol. Chem. 269 : 1821 -1826. ↵ International Chicken Genome Sequencing Consortium...
  7. ...for the portions of the human X chromosome that are syntenic to the Monodelphis chromosomes 4 and 7 and that appear to have conjoined the rest of the X chromosome early in eutherian evolution ( Glas et al. 1999 ) ( Figs. 2B , 3C ; Supplemental Table 1). Moreover, nucleotide substitution rates and overall G...
  8. ...2003 ; Filatov and Gerrard 2003 ; Hellmann et al. 2003 ), possibly indicating a mutagenic effect of recombination. GC and recombination rates are known to covary ( Eyre-Walker 1993 ; Fullerton et al. 2001 ), and it has recently been argued that substitutional GC biases are directly associated...
