Classical, or constitutive (Brown,1966), heterochromatin was first clearly defined by Heitz (1928), and its biological roles have been debated ever since. Constitutive heterochromatin is defined cytologically - whole chromosomes or chromosome segments which maintainneutral-posture 发表于 2025-3-31 02:41:47
Zhongjie He,Hua Li,Karl Erik Birgerssonsolved are large and of fundamental importance. Generally, during meiosis, each pair of homologues must align, associate closely along their length and crossover at least once; then chiasmata must be maintained until homologues can be directed to opposite poles for the first division anaphase, and sSpinal-Tap 发表于 2025-3-31 05:54:23
Wil H. A. Schilders,Agnieszka Lutowskanetic map has been established. In many of the larval tissues of Drosophila the cells become quite large; the DNA replicates, but rather than separating, the sister chromatids remain synapsed through several rounds (up to ten) of replication, resulting in large polytene chromosomes which are easilycharacteristic 发表于 2025-3-31 12:37:06
Antonio C. Ionita,Athanasios C. Antoulasand include several hundred markers each (O’Brien, 1986). It is an arduous task to construct a genetic map and their existence is a tribute to the dedication of the geneticists and breeders who have made it their labor. The techniques of molecular biology have recently offered a more rapid approach宽宏大量 发表于 2025-3-31 16:19:53
