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 ...

the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more loosely distributed and resemble a pile of string.

These cells and others in the body are exact ... The dark bands indicate areas where the structure of the chromosome is dense. Each of the 23 chromosome types has a unique banding pattern.

The epigenetic state of chromatin, gene activity, and chromosomal positions are interrelated. A research team from the IPK Leibniz Institute (IPK) and the Karlsruhe Institute of Technology (KIT) ...

LOY happens due to cell division mistakes, causing the Y chromosome to break apart or be lost. The Y chromosome's unique structure and short ends (telomeres) make it more likely to be trapped in ...

In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like structures called chromosomes. The nucleus of one of your skin cells contains about two metres of DNA ...

However, compaction isn't enough. Cells also need to regulate the chromosome structure to enable its function. For example, when genetic information needs to be accessed, the DNA is locally read off.

Instead of having two copies of each chromosome, as is typical for normal cells ... a map of how alterations in DNA sequences fit in the overall structure of the genome, and it obfuscates cell-to-cell ...

Artificial chromosomes are essentially miniature versions of real chromosomes that can replicate alongside their natural counterparts in host cells. They have the potential to be “incredibly useful ...
