RODENT DNA: COMPARISONS BETWEEN SPECIES

Comparisons between Two Antioxidant Butylated Hydroxytoluene and Glutathione Supplemented Cryopreservation Medium on Human Sperm DNA Integrity

Introduction: Cryopreservation of semen is routinely used in a variety of circumstances including before assisted reproduction treatments, pre- radiation or chemotherapy treatment and etc. The aim of this study was to compare the effect of Butylated hydroxytoluene (BHT) and Glutathione supplemented cryopreservation medium on sperm parameters and amount of DNA fragmentation during the freeze-tha...

Estimating divergence times of Drosophila species from DNA sequence comparisons.

Comparisons between species of the DNA sequences of homologous single copy genes have great potential for use in the reconstruction of phylogenies. The rates of change of nucleotides in introns and " silent " sites in exons are independent of generation time, approximately constant in different lineages, and apparently also constant for different genes (Hayashida and Miyata 1983). From calibrat...

Phenotypic and DNA sequence data comparisons reveal three discrete species in the Ceratocystis polonica species complex.

Ceratocystis polonica and C. laricicola are two morphologically similar species that occur on conifers and reside in the Ceratocystis coerulescens species complex. They, however, represent two ecologically distinct entities. C. polonica causes blue stain on Norway spruce (Picea abies) and other spruce species (Picea spp.) in Eurasia and is associated with the bark beetles Ips typographus, I. ty...

Between-Noun Comparisons

Adjectives are typically felicitous in within-predicate comparisons—constructions of the form ‘X is more A than y’, as in This is bigger than that, but are often infelicitous in between-predicate comparisons—constructions of the form ‘X is more A than (y is) B’, as in *Tweety is bigger than (it is) heavy. Nouns, by contrast, exhibit the inverse pattern. The challenge is to ac...
