Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...

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 ...

Each cell with a nucleus contains chromosomes, which are made from DNA Human body cells each contain 23 pairs of chromosomes, half of which are from each parent. So, human gametes (eggs and sperm ...

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, ...

What determines its gender—in most cases—are its sex chromosomes: two X chromosomes in the nucleus of its original egg cell and it will become a female; a Y and an X chromosome and it will ...

The nucleus acts as the cell's control center ... The human genome is comprised of two sets of 23 chromosomes -- 46 chromosomes in all. Each parent contributes a set. About 97 percent of the ...

A study described the three-dimensional architecture of turtle genomes, which fold in a configuration unlike any other animal observed so far.

New research finds that turtle genomes show a chromatin arrangement that hasn't been observed in other organisms.

Chromosomes are thread-like structures located in the nucleus of every cell in our body, carrying our genetic information. You can think of them as instruction manuals for building and running ...
