Genetic medicine reaches a major milestone with a system capable of inserting entire genes into human DNA. This breakthrough ...

Researchers still do not have a comprehensive picture of the factors that influence gene expression in human cancers.

Centuries after Leonardo da Vinci died far from his Tuscany homeland, pieces of his life — his sketches, his scribbles, his ...

Two proteins, TRF2 and RAP1, work together to block a repair process that would otherwise treat the natural ends of chromosomes as broken DNA and try ... They removed the genes for RAP1 and ...

Additionally, they make clear that DNA looping also affects the supercoiling state of our chromosomes, which directly affects processes like gene expression. Finally, these SMC proteins are ...

the researchers propose that BBP exposure alters gene expression in ways that cause significant damage to the DNA, ultimately leading to lower quality egg cells with abnormal chromosomes.

and is compatible with feasible physical mechanisms for the control of gene expression, as well as for DNA replication, repair, and segregation to daughter cells. Chromosomes can be considered as ...

So, these fossils don’t just show us which genes were active–they show us why.” However, a puzzle still remained. How was it possible that DNA fragments of ancient chromosomes survived for ...

DNA contains the biological instructions that allow for the development, growth, and reproduction of life. Chromosomes, which are located in each cell’s nucleus, contain genes. Each gene ...

It’s also small and seriously weird; it carries few genes and is full of junk DNA that makes it horrendous to sequence. We have known for about 60 years that specialised chromosomes determine ...
