Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study by Weill Cornell Medicine investigators.

In a recent study published in PLOS Pathogens, researchers investigated a highly variable region at residues 203 to 205 in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid ...

Mistakes made during DNA replication can lead to mutations—permanent alterations in the DNA sequence that can have varying effects on the organism, ranging from benign to harmful. The precision of DNA ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell ...

(THE CONVERSATION) A defining characteristic of cancer cells is their immortality. Usually, normal cells are limited in the number of times they can divide before they stop growing. Cancer cells, ...

Many viruses, particularly RNA viruses, mutate at a very high rate per genome per replication. One possible explanation is that high mutation rates are selected to meet the challenge of fluctuating ...

This is the third in a series on the Omicron variant. In part one, we described the potential origins of Omicron. In part two, we described the Omicron Spike protein mutations. Here we describe the ...

Influenza B virus is a significant respiratory pathogen responsible for seasonal influenza. In recent years the B/Yamagata lineage has demonstrated a rapid increase, predominantly featuring the ...

A defining characteristic of cancer cells is their immortality. Usually, normal cells are limited in the number of times they can divide before they stop growing. Cancer cells, however, can overcome ...
