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 ...

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 difference ...

Two RIKEN researchers have discovered how, during cell division, one enzyme helps facilitate the tightly coordinated reorganization of chromosomal DNA into compact structures that can be evenly ...

The genome remains mostly constant during development and ageing. Cells differ in which part of the genome they express. The gene-expression programme is determined by the presence of transcriptional ...

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 asexual to ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

This video explains the stages of mitosis, contrasts them with meiosis and the creation of haploid gametes, and concludes by ...

Researchers have found a molecular mechanism that prevents multiplication of potentially dangerous cells by measuring the duration of mitosis. They have shown that this mechanism -- the Mitotic ...

Embark on an exciting journey to uncover the wonders of cell division as we explore mitosis and meiosis. In this captivating explanation, we'll delve into how cells divide and pass on genetic ...

an organism grows an organism becomes damaged and needs to produce new cells for repair organisms like bacteria reproduce asexually It is essential that any new cells produced contain genetic ...
