A new paper describes how scientists used the tool to identify an important role for TRIM24 in mediating telomere repair after cells divide.

Each time a cell divides, a small section of each chromosome's protective cap—the telomere—is worn away. Most cells use an ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

The cold sore-causing Herpes Simplex Virus (HSV-1) hijacks human cells and reconfigures its DNA within just an hour after ...

In men, the X, with its SHOX, is fully active. So is the Y. This means that a woman, with her two X chromosomes, will have a slightly lower dose of the SHOX gene than a man, with an X and a Y. As ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share ...

Discoveries about the end-replication problem indicate both telomerase and the CST–Polα-primase complex are essential for chromosome protection, suggesting a revision in the science of telomeres and ...

Double trouble at chromosome ends Date: February 28, 2024 Source: Rockefeller University Summary: New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as ...

However, Ohbayashi et al. demonstrate variations in cyanobacterial chromosome replication mechanisms, manifested by regular/irregular GC skew profiles. Here, the genomes of certain free-living species ...

Chromosome 1 is the largest and contains around 2,800 genes. The smallest is chromosome 22 with around 750 genes.
