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' ...

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 ...

Meiosis is a specialized type of cell division in which two rounds of chromosome segregation follow a single round of DNA replication. In diploid organisms, meiosis generates gametes with a haploid ...

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 ...

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 ...

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 ...

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 ...

Geneticists have been debating if meiosis requires only external or internal signals. Although earlier work revealed that an external cue from retinoic acid is needed, new research shows that ...

Mating and meiosis -- the specialized cell division that reduces the number of chromosomes in a cell -- are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, ...

The process of meiosis happens in the male and female reproductive organs. As a cell divides to form gametes: ...

The long-range objectives of our research are to understand the mechanism of meiotic recombination and to determine how this process is coordinated with other events of meiotic prophase. Several ...
