DNA replication behavior in complex organisms may foreshadow leaps in genomic discoveries

... genetic materials identical to parent cells. This duplication occurs in the section of the cell cycle known as the S-phase. Extensive research on the budding yeast, an organism often used in modern cell biology research, had revealed that the replication process is initiated at hundreds of origins in the ...

Features of replication suggest viruses have common themes, vulnerabilities

Linheng Li Lab documents the development of cancer stem cells

... to changes that may increase the number of stem cells and change their position or location," said Dr. Li. "These changes result in crypt fission and budding and can lead to intestinal polyposis and uncontrolled tumor growth." "All of us were very excited to be part of these efforts to reveal basic ...

Evolution and the workaround

... how pathogens and cancer cells mutate to evade the body’s defenses and resist treatment with drugs. The Stowers researchers used the benign budding yeast Saccharomyces cerevisiae as their model organism and deleted a key cell division gene called MYO1. Surely, eliminating this important gene ...
