Causes: LIG4 syndrome is caused by a mutation in the LIG4 gene, which carries the instructions needed to make a protein known as DNA ligase 4. This protein is an enzyme that helps repair a ...

Each of us has enough DNA to reach from here to the sun and back, more than 300 times. How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a ...

POLA2敲低引发复制应激 ：研究人员发现，在果蝇翼盘中敲低 POLA 2 ，会导致 DNA 复制速度减慢。通过 EdU 标记实验，发现表达 POLA 2 -i 的细胞 EdU 水平较低，且处于 S 期的时间更长。同时，POLA 2 的敲低还会造成单链 DNA（ssDNA）积累，RPA1-GFP 标记显示，POLA 2 敲低的细胞中出现了 RPA1-GFP 焦点，这些都表明 POLA 2 ...

The number of home DNA test kits offering nutrition and diet advice matched to your genes is growing. They’re based on the idea that each of us responds to foods differently, in part due to our ...

Stanford Medicine researchers sifted through thousands of single nucleotide mutations in DNA to identify fewer than 400 that are functionally associated with inherited cancer risk. Thousands of ...

Ancient DNA is telling us more and more about humans and environments long past. Could it also help rescue the future? Eske Willerslev was on a tour of Montreal’s Redpath Museum, a Victorian-era ...

The prosecution’s most important piece of evidence is a DNA sample taken from a knife sheath left at the crime scene. Investigators then used investigative genetic genealogy, or IGG, a forensic ...
