(1) On the basis of genetic, phenotypic and physiological criteria, these mutants are divided into four groups: 1) the cytochrome aa3 and b deficient "poky" variants that are defective in mitochondrial ribosomes assembly, 2) the cytochrome aa3 deficient mutants, [mi-3] and [exn-5], that appear to have genetic lesions affecting a component of a regulatory system controlling cytochrome aa3 synthesis, 3) the cytochrome aa3 and b deficient "stopper" mutants with physiological lesions that probably affect mitochondrial protein synthesis, and 4) cni-3, a mutant that is constitutive for an inducible mitochondrial cyanide-insensitive oxidase in spite of having a normal cytochrome mediated electron-transport system.
(2) Cell respiration in wild type and poky was studied as part of a long-term investigation of cyanide-resistant respiration in Neurospora.
(3) Six independently isolated Group 1 extranuclear mutants, namely [exn-1], [exn-2], [exn-4-a1, [stp-b1], [SG-1] and [SG-3-A1, which have growth and cytochrome phenotypes similar to [poky] also were found to be deficient in small subunits of mitochondrial ribosomes.
(4) Seven nonallelic nuclear suppressors of [poky] result in increased concentrations of the mt small rRNA and pre-rRNAs, but do not restore the ability to synthesize small rRNAs having the correct 5' ends.
(5) Group I consists of 8 female-fertile variants with both poky-like growth and cytochrome defects.
(6) Two-dimensional gel electrophoresis was used to examine mit ribosomal proteins from [poky] and six additional extra-nuclear mutants with defects in the assembly of mit small subunits.
(7) Six nuclear suppressors of the (poky) cytoplasmic mutant (sup-1, sup-3, sup-4, sup-5, sup-10, sup-14) have been obtained in Neurospora crassa.
(8) However, the transmission of the [poky] mutation does not appear to be correlated with the transmission of either of these insertions or of other physical markers.
(9) Mitochondria from the cytochrome-deficient mutant poky carried out substrate-driven K+ uptake at reduced rates, but oligomycin-sensitive, ATP-driven K+ uptake at rates about 60% greater than those shown by wild-type mitochondria.
(10) But actually Chote's team is only about 20-strong and they operate from a rather poky office on Victoria Street.
(11) We have compared the adenosine triphosphatase (ATPase) activity of mitochondria prepared from wild-type Neurospora crassa and from poky, a maternally inherited mutant known to possess defective mitochondrial ribosomes and reduced amounts of cytochromes aa3 and b. poky contains two distinct forms of mitochondrial ATPase.
(12) Pokie Nation, set to air next week on the ABC, has been edited to amend the claim.
(13) In all these experiments, no difference was detected between wild type and poky in base sequence or methylation of either 19 S or 25 S RNA.
(14) The six suppressors are nonallelic, suppress the phenotypic effects of (stp-Bl) in addition to (poky), but have no effect on the phenotype expression of the (mi-3) cytoplasmic mutant.
(15) An analysis of the paramagnetic components present in mitochondria isolated from the poky mutant of Neurospora crassa is described.
(16) Orta filmed the death of Eric Garner , capturing the moment the 43-year-old was placed in a banned chokehold by an NYPD officer and uttered his last words: “I can’t breathe.” Lawyers Ken Perry and William Aronin sit in the poky downtown Manhattan apartment that serves as their office.
(17) The mitochondrial phenotype of [poky] and other extranuclear Neurospora mutants is known to predominate over that of wild type in heteroplasmons.
(18) They are not allowed to draw in court, so they must observe, make notes about someone’s characteristics and clothes, and then retreat to a poky press room where they sketch and colour at high speed.
(19) The residual small rRNAs in [poky] appear to be synthesized via the upstream promoter(s), but are missing 37-44 nucleotides from their 5' ends, indicating either that pre-rRNAs are processed abnormally or that abnormal 5' RNA ends are unstable.
(20) The ribosomal defect shows an extrachromosomal pattern of inheritance in crosses of poky with wild type.

(n.) A ropedancer's balancing pole.
(n.) A long boat hook by which barges are propelled against the stream.
Example Sentences:
(1) For example, mispronunciations produced by changing the voicing of a word-initial stop (e.g., "boy" to "poy") were detected about 70% of the time, while changes in voicing of a word-initial fricative (e.g., "voice" to "foice") were detected about 38% of the time.
(2) Taken together with DNA sequence information (Y. Sato, F. Poy, G. R. Jacobson, and H. K. Kuramitsu, J. Bacteriol.
(3) We have isolated a number of genes encoding them; 11 POX genes encoded independent PXPs and three POY genes were likely to encode three other PXPs.
(4) Hemolytic anemia was experienced in 8 cases with Starr-Edwards (S-E) 2320 (n = 7) and Omni-Science (n = 1) both in the aortic position and those prostheses were replaced at 1-9.6 (mean 4.5) postoperative years (POY).
(5) Fourteen Hancock (H) and 3 Angell-Shiley (A-S) bioprostheses experienced tissue failure of valves and they were subjected to reoperation at 3.2-10.0 (mean 6.5) POY.
