| y chromosome evolution in the subgenus mus (genus mus). | a 305 base pair dna sequence isolated from the y chromosome of the inbred mouse strain c57bl/10 was used to investigate the pattern and tempo of evolution of y chromosome dna sequences for five species in the subgenus mus, including mus spretus, mus hortulanus, mus abbotti, mus musculus and mus domesticus. variation in hybridization patterns between species was characterized by differences in fragment lengths of both intensely and faintly hybridizing fragments, whereas variation in hybridization ... | 1989 | 2543607 |
| evolution of mouse chromosome 17 and the origin of inversions associated with t haplotypes. | mouse t haplotypes are variant forms of chromosome 17 that exist at high frequencies in worldwide populations of several species of house mouse. they are known to differ from wild-type chromosomes with respect to two relative inversions referred to as proximal and distal. an untested assumption has been that these two inversions originated in the chromosomal lineage leading to present-day t haplotypes. to investigate the evolutionary origins of these inversions and the possibility of additional ... | 1989 | 2717616 |
| a repeated segment on the mouse y chromosome is composed of retroviral-related, y-enriched and y-specific sequences. | we report the isolation and characterization of two recombinant clones containing dna derived from the y chromosome of the c57bl/10 inbred mouse strain. both clones were isolated from a lambda phage library derived from a partial ecori digest of c57bl/10 male dna using the murine retrovirus m720. characterization of these clones showed they were derived from a repeated segment present on the c57bl/10j y chromosome that contains sequences found elsewhere in the genome. in addition, one clone cont ... | 1989 | 2731728 |
| altered turnover of hypoxanthine phosphoribosyltransferase in erythroid cells of mice expressing hprt a and hprt b alleles. | we have previously shown that mice expressing hprt a allele(s) have erythrocyte hypoxanthine phosphoribosyltransferase (hprt) levels that are approximately 25-fold (mus musculus castaneus) and 70-fold (mus spretus) higher than in mice that express the hprt b allele (mus musculus domesticus; c57bi/6j; c3h/heha), and that these differences in erythrocyte hprt levels are due to differences in the turnover rates of the hprt a and b proteins as reticulocytes mature to erythrocytes. we show here that: ... | 1987 | 3609725 |
| [polymorphism of t-specific dna elements of the proximal part of chromosome 17 in mice of mus genus]. | to study structural organization and polymorphism of the proximal part of chromosome 17, a hybridization analysis of dna from mice of different origin was carried out using four t-specific probes. results of the analysis allow us to conclude that the dna element copy number is quantitatively unstable and differs in distribution in both newly formed recombinant haplotypes and in wild-type chromosome 17. probe tu66 was used to study d17leh66-element organization of mus abbotti and mus hortulanus m ... | 1995 | 7622026 |
