Nuclear Dimorphism: Two Peas in a Pod
نویسندگان
چکیده
The macro- and micronuclei of Tetrahymena reside in the same cytoplasm but are about as different as night and day. This extreme case of nuclear dimorphism can now be partially attributed to differences in the subunit compositions of their nuclear pore complexes.

The application of individually and socially distributed cognition in workplace studies: two peas in a pod?
This paper compares and contrasts two forms of distributed cognition one looking at how an individual interacts with one or more artefacts, the other looking at how groups of people interact with or without artefacts. Whilst the two approaches have many similarities, they can be seen to have significant practical and theoretical differences and merit very different approaches, particularly in t...
متن کاملPrinciples of Inheritance and Variation
Gregor Mendel. Conducted hybridization experiments on garden peas for seven years (1856 – 1863) and proposed laws of inheritance. Mendel conducted artificial pollination/cross pollination experiments using several true-breeding pea lines. A true breeding line is one that, having undergone continuous self-pollination for several generations. Mendel selected 14 true-breeding peas’ plant v...
متن کاملMetabolic syndrome and hypogonadism--two peas in a pod.
Testosterone deficiency is highly prevalent in up to 50% of men with the metabolic syndrome and type 2 diabetes mellitus. Low testosterone levels in men appear to be an independent cardiovascular risk factor and predictor of subsequent development of the metabolic syndrome. Reciprocally, the metabolic syndrome leads to a decrease in testosterone levels. This review provides an account of the pa...
متن کاملSexual dimorphism in digit length ratios of the second to fourth digits (2D:4D) in two species of green toads (Pelobates syriacus Boettger, 1889 and Bufo viridis (Laurenti, 1768))
Sexual dimorphism in the ratio of digits length is a morphological feature resulted from the interaction between sex hormones and prenatal Hox genes, the latter is known to control the development of both limbs and genitals. The status of this trend and ratios have been investigated in various animal groups, including humans, other mammals, birds, reptiles, and amphibians. In this study, the bo...
متن کاملExperimental and Theoretical Investigation of Drying of Green Peas in a Fluidized Bed Dryer of Inert Particles Assisted by Infrared Heat Source
Drying of green peas in a Fluidized Bed Dryer (FBD) with inert particle, heated by combined sources of hot air and InfraRed (IR) radiation, has been experimentally and theoretically studied. For this purpose, an experimental set up was constructed. This setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. Some infrar...
