James P Terry,A Y Annie Lau,Samuel EtienneThe development of chromosome banding techniques has resulted in considerable knowledge of the comparative cytogenetics of many groups of mammals. In order to assess the significance of the results obtained from studying marsupial cytogenetics it is necessary to indicate the special features of this group of mammals.Engaging 发表于 2025-3-28 21:44:29
Molecular dissection of the , chromosomeWe have developed methods for gene isolation which do not depend on previous knowledge of the product of the gene (Bender . 1983). These protocols, which we called “chromosomal walking and jumping” are now routinely used in most molecular genetics laboratories.捐助 发表于 2025-3-29 01:45:28

Genetics of heterochromatin in , and maizeitutive heterochromatin. Both are late-labeling with .H-thymidine in the cell cycle. Facultative heterochromatin is a developmental imprint like the late-labe ling X chromosomes. In modern terms, constitutive heterochromatin is defined as the highly repeated DNAs usually made up of short repeats ofAwning 发表于 2025-3-29 13:34:19
Chromosome accommodation to integration of foreign DNAlted in the development of selection systems for identification of DNA transformed cells. The discovery of covalent linkage between chromosomal DNA and DNA introduced by DNA-mediated transfer led to new approaches for gene mapping and studies of gene regulation in mammalian cells (reviewed in PellicMisnomer 发表于 2025-3-29 15:33:23

Polytene chromosomes of , arms are uniformly replicated, there are exceptions that provide insights into chromosome structure. We discuss three exceptional sequences that are under-replicated and whose cytogenetic locations correspond to constrictions and ectopic fibers at their respective sites, which have been described pEtymology 发表于 2025-3-30 03:23:44
