Meiotic recombination drives eukaryotic sexual reproduction and the generation of genome diversity. Tetrad analysis, which examines the four chromatids resulting from a single meiosis, is an ideal ...

Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis. In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, ...

Scott Keeney, Bernard de Massy, Maria Jasin and colleagues report a method to perform tetrad analysis (analysis of all four chromatids from a single meiosis) in mouse and analyzed two ...

How Cells Divide: Mitosis vs. Meiosis by Rick Groleau As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced.

How Cells Divide. By Rick Groleau; Posted 10.09.01; NOVA; Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes.

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 ...

Researchers at the IPK Leibniz Institute have discovered a previously unknown protein that is central to plant reproduction. The protein SCEP3 enables plants to mix and precisely distribute their ...

Meiosis is a specialized cell division process required to generate gametes, the reproductive cells of an organism. During meiosis, paternal and maternal chromosomes duplicate, pair, and exchange ...

After dazzling sky watchers Monday night, get ready for round two. Set your calendar for October 8th, when the second total lunar eclipse in this "Blood Moon" tetrad occurs, but this one is for ...
