How is the same process responsible for genetic recombination and diversity also the cause of aneuploidy? Understanding the steps of meiosis is essential to learning how errors occur. Researchers' ...

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 ...

Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

All cells arise from other cells through the process of cell division. Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores and sperm and ...

Multicellular eukaryotes and single-celled sex cells reproduce by a process called meiosis. In this process, the number of chromosomes in a mother cell is halved to produce gametes, cells that fuse ...

There is a high unmet need for accessible, affordable, and high-quality fertility care, as approximately 1 in 6 people are affected by infertility worldwide. While meiotic failure is a major cause of ...

A team deciphers complicated mechanism underlying genetic diversity. Movies such as 'X-Men,' 'Fantastic Four,' and 'The Guardians,' which showcase vibrant mutant heroes, have captivated global ...

Researchers at Oregon Health & Science University (OHSU) have developed a remarkable new way for making human body cells ...

In a study of meiosis in budding yeast, a research team found that yeast senses temperature changes by increasing the level of DNA negative supercoils to increase crossovers and modulate chromosome ...
