The majority of eukaryotic promoters utilize multiple transcription start sites TSSs. Aryee and Rafael A. In population epigenomics, comparable tools are rare although the epigenome can vary at several le Whether RIP affects core genomic sequence in important ways is unknown.
A partnerless, unpaired sex chromosome e. Yet by definition, sex chromosomes of the heterogametic sex lack a homologous partner.
Current Biology. The cytogenetic marker, Idhis located at the distal end of our Y chromosome assembly, remarkably consistent with the placement of Idh in the cytogenetic map [ 32 ], indicating stratum one is no longer located at the distal end of the Y chromosome as it is on the X chromosome.
Reads were only retained if they were at least 75 nucleotides long after trimming. Heteromorphic sex chromosomes definition in Gladstone G Sex determination in the larvae of the parasitic barnacle Heterosaccus lunatus : an experimental approach.
