We find that at the time of its origin, the woolly mammoth had already acquired a broad spectrum of positively selected genes, including ones associated with hair and skin development, fat storage and metabolism, and immune system function.
Chromatoid bodies (CBs) are characteristic spermatid organelles, which were suggested to function in RNA storage and small RNA processing, but whose functions remain largely unknown.
Background: Hypotonicity stimulates transepithelial ion and water flux in the Drosophila renal tubule through unknown mechanisms. Results: The with-no-lysine (WNK) and Ste20-related proline/alanine-rich (SPAK)/oxidative stress response (OSR…
En criptografía, X.509 es un estándar UIT-T para infraestructuras de claves públicas (en inglés, Public Key Infrastructure o PKI). [1 ] X.509 especifica, entre otras cosas, formatos estándares para certificados de claves públicas y un…
CTF4 and CTF18 are required for high-fidelity chromosome segregation. Both exhibit genetic and physical ties to replication fork constituents. We find that absence of either CTF4 or CTF18 causes sister chromatid cohesion failure and leads…
