Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

There are two types of chromatin, euchromatin and heterochromatin, that vary with the stages of the cell cycle. In particular, euchromatin with rich active genes localizes to the interior of the ...

Scientists trying to solve the ultimate puzzle -- the architecture of the human genome -- have snapped another piece into place. They have developed a model to explain one part of the mechanism, the ...

A Japanese researcher has investigated the contributions of active deformation dynamics of cell nuclei using the Brownian motion theory. A Japanese researcher has investigated the contributions of ...

A detailed map of human chromosomes within the nucleus is presented in Nature this week. This resource provides a foundation for an improved understanding of how the physical layout of human DNA is ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around ...

Chromosomes carry our basic genetic material. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Your DNA blueprint (genome) doesn't exist as one ...

The cell nucleus is the site of many important biological functions of the eukaryotic cell. These processes include transcription, replication, splicing and ribosome biogenesis. The effect of these ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In ...

Within the hallowed walls of the cell, conflict simmers; a tenuous peace, and perhaps its very survival, rest on the slimmest of margins. Housed within the cell’s inner sanctum – the nucleus – is its ...
