For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit ...

The human body is made up of billions of cells. These cells grow and divide through a process called cell division. There are two types of cell division: mitosis and meiosis. Mitosis is a type of cell ...

During meiosis, paternal and maternal chromosomes duplicate, pair, and exchange parts of their DNA in a process called meiotic recombination. In order to mediate this exchange of genetic material, ...

In the choreography of meiosis—the process responsible for sex cell division in all eukaryotic life—the pairing of homologous chromosomes (homologs) is essential. Errors in this process can lead to an ...

During sexual reproduction, chromosomes transmitted via the mother and the father's gametes (egg and sperm) are shuffled to produce a genetic combination unique to each offspring. In most cases, the ...

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 ...
