In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid. In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called ...

Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...

the cell must duplicate its DNA – its genome – and segregate it equally into two new daughter cells. To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell ...

The genetic information within each of these daughter cells is identical. Though the genetic code of a human being is contained within 46 chromosomes, only half of this number exists within the ...

The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious ...

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 ...

ChromTR, a novel framework for chromosome detection in metaphase cell images, represents a significant advancement in the ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Instead of having two copies of each chromosome, as is typical for normal cells, the cancer cells had anywhere from one to as many as five or six copies; and sometimes there were parts of chromosomes ...

Why are the human sex chromosomes called “X” and “Y,” while the other 22 chromosomes are identified only by numbers? The answer begins in the late 1800s, when insect gonad cells, whose large ...

"The X and Y chromosomes have traditionally been viewed primarily as determinants of biological sex, but they're much more than that. They contain genes that affect how cells function in ways we ...
