Murine leukemia virus (MLV)-based vector RNA can be packaged and propagated by the proteins of spleen necrosis virus (SNV). We recently demonstrated that MLV proteins cannot support the replication of an SNV-based vector; RNA analysis revealed that MLV proteins cannot efficiently package SNV-based vector RNA. The domain in Gag responsible for the specificity of RNA packaging was identified usin...
Env C2/V3, gag p17/p24, pol protease, and RT regions of HIV-1 isolates recently obtained from 25 HIV-1 seropositive individuals from Ho Chi Minh City (Vietnam) were studied, and genes subtypes were determined by DNA sequence analyses. Twenty-three isolates out of 25 were identified as belonging to subtype E, now recognized as circulating recombinant form 1 (CRF01_AE). The motif at the top of th...
Replicating the end of a linear chromosome poses a problem that can be solved by the combined action of the general DNA replication machinery, DNA repair factors, telomere proteins and telomerase. In this issue of The EMBO Journal, a new study by Moser et al examines the timing of replication, repair and telomere factor association with fission yeast telomeres. The study demonstrates the dynami...
D NA mismatch repair (MMR) is an important postreplicative repair mechanism that removes DNA polymerization errors and is responsible for increasing the fidelity of genome replication by orders of magnitude. Defects in MMR lead to the most common form of hereditary colon cancer and a variety of sporadic cancers (1–3). One of the main features of MMR is its ability to distinguish old and new DNA...
Determining the amount of trophy in aquatic ecosystems is important because increasing the availability of nutrients is affectings all levels of aquatic ecosystems as well as changes in species abundance, migration, reduce in biodiversity and changes in the structure and composition of communities. Therefore, there should be a proper method for determining the trophy state or production in t...
of a collaboration between the synthetic capacities of Massachusetts Institute of Technology multiple polymerases. Two types of polymerases are Cambridge, Massachusetts 02139 required: primases, which start chains, and replicative polymerases, which synthesize the majority of the DNA (Kornberg and Baker, 1992). The replication fork, how-Synthesis of all genomic DNA involves the highly coordi-ev...
