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 ...

Without centromeres, cells cannot divide properly and the overall process of mitosis fails. Why are these small chromosomal regions so essential to such a major cellular process? With a few ...

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

The improper segregation of chromosomes during cell division leads to abnormalities that disrupt the proper functioning of the cell. Cells with an abnormal number of chromosomes consequently ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from ...

Among the many marvels of life is the cell’s ability to divide and thus enable organisms to grow and renew themselves.

Interphase The cell spends most of its life in this phase. The DNA in chromosomes copies itself ready for mitosis. Prophase The DNA in chromosomes and their copies condenses to become more visible.

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 ...

Each replicated chromosome is made up of two identical strands called chromatids that are joined together. Each chromatid is a full length DNA molecule. The stages outlined in the following ...

Ergonomic. Wireless. Low-latency. Minimalist. Efficient. How far do you go when you design your own open-source keyboard? Checking off these boxes and providing the means for others to do so ...

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 ...

Welcome to Mitosis vs. Meiosis. This half of the screen illustrates mitosis—the division of a cell's nucleus. Along with cytokinesis (the division of the rest of a cell), mitosis results in a ...
