FEN1 Ensures Telomere Stability by Facilitating

The reactions were subject to a phenol/chloroform/isoamyl alcohol extraction and the DNA was precipitated with isopropanol followed by a 70% ethanol wash To verify that the products were generated by semi-conservative replication additional samples were digested after precipitation with 10 units of DpnI (New England Biolabs) for 5 min at 37

Genes located in a chromosomal inversion are correlated

The white‐throated sparrow (Zonotrichia albicollis) a common North American songbird provides a unique model to study the relationship between genes and behavior because it exhibits a chromosomal polymorphism linked to a behavioral polymorphism In this species the second chromosome occurs in two arrangements ZAL2 and ZAL2 m (Thorneycroft 1975)

Analysis of a viral metagenomic library

Viruses have a profound influence on both the ecology and evolution of marine plankton but the genetic diversity of viral assemblages particularly those in deeper ocean waters remains poorly described Here we report on the construction and analysis of a viral metagenome prepared from below the euphotic zone in a temperate eutrophic bay of coastal California We purified viruses from
