Humans have 46 chromosomes. Each of these chromosomes has a specific structure, which can be ascertained by a number of techniques. This node tells the story of why it took so long for scientists to ...

The human genome is made up of 46 chromosomes, each of which has a length of about 100–200 million base pairs, base pairs being the building blocks of the DNA double helix. Even during interphase, the ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

Scientists have finally uncovered the exact DNA sequence where human chromosomes fuse to form Robertsonian chromosomes, a mystery that has puzzled researchers for over a century. Using advanced genome ...

Generally, a person is born with 2 sets of chromosomes (46 chromosomes). So, what if the fetus has 69 chromosomes (three sets)? This condition is called triploidy. A fetus with this extra chromosome ...
