Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes ...

DNA is organized in segments on chromosomes called genes. Humans typically have ... At the center of each cell lies a nucleus, which contains the information the cell needs to do its job.

The structure of a cell’s nucleus has long served as a visible clue to whether a cell is healthy or affected by disease.

Save guides, add subjects and pick up where you left off with your BBC account. The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is ...

Despite being densely packed to fit into the nucleus, chromosomes storing our genetic information are always in motion. This allows specific regions to come into contact and thereby activate a gene.

This knowledge is crucial for analyzing how DNA structure ... genome feature in the cell nucleus -- and connects them to gene expression patterns. In human cells, chromosomes aren't arranged ...

Inside the nucleus are 23 pairs of chromosomes. These are long strings of ... But if the DNA damage occurs to a gene that makes a DNA repair protein, a cell has less ability to repair itself. So ...

and genes are pieces of genetic information that cells use to make a particular product, such as a protein. DNA is located inside the nucleus of a cell, where it's packaged into chromosomes ...
