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.

Finnish researchers use AI to accelerate colorectal cancer diagnostics

Researchers at the Faculty of Information Technology at the University of Jyväskylä have used artificial intelligence to speed up the analysis of colorectal cancer samples and predict the functioning of the cells' DNA repair mechanism.

Research reveals a link between defective DNA repair and immune-driven inflammatory disease

Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature aging and embryonic lethality in mice.

Researchers create the most detailed 3D maps of the human genome

In a landmark effort to understand how the physical structure of our DNA influences human biology, Northwestern investigators and the 4D Nucleome Project have unveiled the most detailed maps to date of the genome's three‑dimensional organization across time and space, according to a new study published in Nature.

New method reveals how human cells initiate DNA replication

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, and genetic disorders. Therefore, understanding how cells replicate their DNA is crucial for elucidating fundamental biological processes, diseases, and even evolution.

Researchers discover new mutation hotspot in the human genome

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we study genetics and disease.

Dysfunction in chromosome-stabilizing protein identified as a cause of deadly illnesses

New research from the University of Wisconsin–Madison reveals that dysfunction in a protein essential to maintaining stability in our chromosomes may be responsible for serious - and sometimes deadly - diseases.

Nuclear binding protein identified as key contributor to trisomy 21-related CHDs

Three copies of chromosome 21 causes Down syndrome (DS), and roughly half of children born each year in the United States with DS-approximately 2,600-also have congenital heart defects (CHDs).

Newly identified protein acts as a traffic controller for DNA replication

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according to a study published in Nature.
