CD8 T cells are activated when their T-cell receptor (TCR) recognizes a peptide presented in the context of the cognate MHC-I molecule on an antigen-presenting cell. This interaction is a key element ...

Scientists say their work on a critical step in DNA replication will provide new insights into a fundamental process of life and driver of many different diseases, including cancer. They report the ...

This is a preview. Log in through your library . Abstract Two general models have been proposed for DNA replication. In one model, DNA polymerase moves along the DNA (like a train on a track); in the ...

In the DNA fiber assay used in this study, cells labeled with IdU (green) and CldU (red) nucleotide analogs were sorted into substages of S phase before being subjected to the DNA fiber assay. This ...

June 27 (UPI) --Scientists have developed a more effective way to highlight and watch the molecular machinery inside a cell. Using fluorescent biomarkers, researchers successfully observed the ...

We propose a simple model for interaction between gene candidates in the two strands of bacterial DNA (deoxyribonucleic acid). Our model assumes that 'final' genes appear in one of the two strands, ...
