In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and ...

Numerous other features and processes associated with modern eukaryotic cells evolved during this time ... roles in highly conserved processes within the nucleus itself, such as DNA replication and ...

In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope). Eukaryotic cells also contain a ...

An international collaboration between four senior scientists from Mainz, Valencia, Madrid, and Zurich has published ...

all the way down to the level of the atoms that make up a single DNA base. The human body contains about 100 trillion cells, each working together in a complex symphony of interactions.

additional DNA is found on one or more rings called plasmids. Eukaryotic cell DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. Prokaryotic cell DNA is a single molecule ...

The DNA of human cells consists of a sequence of about 3.1 billion building blocks. Cells go to great lengths to maintain the ...

The enormously long genomic DNA molecules in eukaryotic organisms must be tightly ... mitosis to protect the genetic ...

Molecular biologist Dirk Remus studies how cells normally copy their DNA to better understand how the process goes wrong in cancer. G-quadruplex-stalled eukaryotic replisome structure reveals helical ...
