A team led by Professor Kazuhiro Maeshima of the National Institute of Genetics (ROIS) and SOKENDAI in Japan has developed a ...

DNA is found in nearly all living cells. However ... thereby compacting it enough to fit inside the nucleus (Figure 8). Together, eukaryotic DNA and the histone proteins that hold it together ...

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

One hypothesis is that the DNA loops could determine which genes are switched on in the cell. Inside a nucleus, chromosomes jumble together like a game of Twister. This can bring regulatory elements, ...

With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's.

In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear ...

DNA can be cut up and separated, which can form a 'barcode' that is different from one person to the next. Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs.

A novel technique to visualize gene-active and gene-repressive DNA regions in living cells, developed by a ...
