(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.

(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.

(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.
