July 19, 2022 The Prussian carp is considered one of the most successful invasive fish species in Europe. Its ability to reproduce asexually gives it a major advantage over competing fish. An international ...
Nov. 17, 2021 Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm ...
Aug. 13, 2021 The initials BRCA2 may be best known for a gene associated with many cases of breast cancer, and the protein encoded by the BRCA2 gene is critical to repairing breaks in DNA. The breakdown of this ...
June 9, 2021 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, ...
Mar. 13, 2023 Meiotic recombination assures genetic variation during breeding. During meiotic prophase I, chromosomes are organized in a loop-base array by a proteinaceous structure called meiotic chromosome axis ...
Aug. 18, 2022 Two novel hypotheses have been proposed that address the 'two-fold cost of sex': one of the biggest enigmas in the evolution of sexual ...
May 25, 2023 The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for ...
Dec. 7, 2022 Modern eukaryotic cells contain numerous so-called organelles, which once used to be independent bacteria. In order to understand how these bacteria were integrated into the cells in the course of ...
May 11, 2021 Researchers have discovered how microbes responsible for human African sleeping sickness produce sex ...
Aug. 24, 2021 Certain proteins may have evolved to tamp down 'cheating' during meiosis, the cell-division process that gives rise to eggs and sperm. While chromosomes can tip the scales in their favor of ...
