EU828 C. elegans dhc-1(or195) I. Show Description
Homozygous or195 hermaphrodites make 100% dead embryos at 26C. One-cell embryo has a very small but bipolar spindle, severe chromosome segregation defect. Maintain at 15C. Previously called spd-4. 2/06: From Bruce Bowerman: The or195 mutation changes base 10,679 of the cosmid clone T21E12 from a C to a T. This corresponds to dhc-1 cDNA nucleotide 9599 (WS153) , which is the center nucleotide of codon 3200. This codon changes from Serine in N2 to Leucine in or195 (S3200L). Note: this is not the same mutation for or195ts that we reported in Hamill et al, 2002(Dev Cell 3, 673-684). The mutation reported in our paper is not present in this strain. We apologize for the confusion. The pairs dhc-11a,b amplify the mutated fragment in dhc-1(or195). The mutation is near the center of this fragment; a clean (gel purified) DNA prep helps get a good read of it. dhc-11b: 5' aacagacgcacgattgacct 3'. dhc-11a: 5' ctcaaatcaaggaaggagct 3'.
