Example sentences for: tab
How can you use “tab” in a sentence? Here are some example sentences to help you improve your vocabulary:
The same crosses were also used to determine if Tab +was recessive or dominant: for every tab mutant, haploid cdc15Δ tab [pMET3-cdcl5-2, URA3] and diploid cdc15Δ/cdc15Δ tab/+ [pMET3-cdc15-2, URA3 ] cells were pre-grown on YPD (1% yeast extract/2% peptone + 2% glucose) at 25°C for 2-3 days, spotted in 5-fold serial dilutions onto SD+5-FOA plates, and the number of 5-FOA resistant colonies from the diploid was divided by that from the haploid to obtain ratio P. The mutant was defined to be dominant if P= 0.1-1, semi-dominant if P= 0.01-0.
This analysis revealed TAB1 to be MTR10, and TAB2 to be YJL076W (NET1).
Both MTR10 (TAB1 ) and SRP1 belong to the nuclear transport receptor/adaptor family (reviewed by [ 38 ] ). Mutant srp1-31 and mtr10 tab 1-1cells accumulate the ribosomal protein Rpb11b in the nucleus [ 39 ] . Thus, to evaluate a potential link between nuclear transport and the tab phenotype, we evaluated the localization of Rpl11b-GFP [ 39 ] in all tab mutants.
The recessive tab mutants exhibited a ts growth phenotype that co-segregated with the Tab +phenotype.
The recessive tab mutants are likely to represent reduction-of-function mutations in genes that inhibit exit from mitosis, and the dominant TAB mutants are likely to result from gain-of-function mutations in genes that promote exit from mitosis.
