DNA Replication News and Research

RSS

DNA replication, the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.

Proteins’ movement and the spread of antibiotic resistance

Umeå University researchers have figured out how a particular type of protein travels during DNA replication. The discovery could affect the current understanding of how bacteria propagate antibiotic resistance genes.

Figuring out how cells safeguard their genomes during replication

Cells zealously protect the integrity of their genomes, because damage can lead to cancer or cell death. The genome, a cell’s complete set of DNA, is most vulnerable while it is being duplicated before a cell divides.

New insights into cell health and disease

Scientists from Weill Cornell Medicine have discovered a protein that not only prepares DNA for replication but also controls the replication process. The research, which was published on January 5th, 2023, in the journal Molecular Cell, resolves a puzzle that has long-baffled biologists.

Effective anticancer strategy for selective killing of cancer cells

A study team headed by Dr Yuanliang Zhai from The University of Hong Kong’s (HKU) School of Biological Sciences and his associates from The Hong Kong University of Science and Technology (HKUST) and Institut Curie in France discovered a new mechanism of the human MCM2-7 complex in controlling replication initiation, which can be employed as a unique and effective anticancer method with the potential for selective death of cancer cells.

Researchers gain insights into how density may change gene expression in some insects

A grasshopper hatched in a crowded environment may look and behave differently than a grasshopper hatched in isolation -; even if they have the same genes.

Revealing the unappreciated role of POLQ in responding to DNA replication stress

Researchers at the Francis Crick Institute, in partnership with Artios, have discovered how an enzyme involved in DNA repair (POLQ) becomes critical to the survival of some tumors when the cancer cells lose the ability to employ a more frequent way of DNA repair.

Revealing the functional significance of DDX41 in great detail

The DDX41 gene encodes the nuclear enzyme DEAD-box-type RNA helicase. Hematopoietic malignancies are caused by DDX41 mutations. However, the mechanism behind the development of this malignancy remains unknown.

Enzymes hold the answer to understanding how DNA mutates

According to recent research from the University of Surrey, enzymes, which are essential for regulating how cells replicate in the human body, could be the very component that encourages DNA to spontaneously mutate, leading to potentially permanent genetic errors.

Revealing cancer development in people carrying inherited BRCA1 mutations

Researchers from Weill Cornell Medicine have discovered that people who inherit a mutant copy of the BRCA1 gene may develop mutations and cancer due to error-prone DNA replication and repair.

A strong enzyme that functions similar to a Swiss army knife

Blue-green algae, also known as cyanobacteria, have a superpower that likely contributes to their extreme success as waterway invaders. They have a remarkable capacity to store nitrogen and energy in their cells for use when necessary.

Yale and uOttawa researchers partner to solve a puzzle rooted in the deepest past of evolution

For decades, scientists have been trying to unravel an enduring mystery of structural biology: Why do two otherwise identical protein forms found in everything from plants, amphibians and human beings hang onto a slight variation across the mighty span of evolution?
