To the point. DNA packaging: DNA exists in different states in order to fulfill different functions in the cell nucleus. A research team has now discovered a molecular switch that controls the ...

How 'jumping genes' infiltrate DNA during cell division. Story by Science X staff • 1d. V iruses are known to use the genetic machinery of the human cells they invade to make copies of themselves.

Researchers at the Centre for Genomic Regulation (CRG) reveal that metabolic enzymes known for their roles in energy production and nucleotide synthesis are taking on unexpected "second jobs ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be constantly folded and packaged. When it is time for cell division, and ...

Loops within loops. From their data, the scientists realized that during cell division, DNA forms loops in two stages. First, it forms stable large loops, which then subdivide into smaller, short ...

As the authors explained, abnormal DNA content is one of the most common characteristics of cancer cells, with recent evidence suggesting that 35 to 40 percent of tumors go through a whole-genome ...

Cell division: Before commitment, a very long engagement Date: June 27, 2024 Source: ... A DNA-repair function could benefit cancer cells as well as healthy cells, Dr. Meyer noted.

In the case of DNA, if this overwinding is not dealt with, essential processes such as copying DNA and cell division grind to a halt. Fortunately, cells have an ingenious solution to carefully ...
