The nature and origin of mutations which block a temporal sequence for genic expression in paramecium.
HERE is a temporal sequence for the expression of two genetically independTent loci in Paramecium bursaria. This sequence was brought to light by demonstrating differences in the competence for mating among cells derived at successive intervals during the vegetative growth of exconjugant clones ( SIEGEL and COHEN 1963). The junctional linkage of the two genes was suggested by the discovery that...
متن کاملThe Genic Control of Mating Types in Paramecium Bursaria.
Jennings"l discovery of a system of multiple mating types in Paramecium bursaria in 1938 followed closely Sonneborn's2 initial description of mating types in P. aurelia. The detailed and brilliant experimental analyses carried out by Jennings3 and directed toward an understanding of mating type inheritance and determination in this organism did not result in a satisfactory explanation for the v...
متن کاملEctopic Expression of Embryo/Cancer Sequence A (ECSA) in KYSE-30 Cell Line Using Retroviral System
Background Human preimplantation embryonic cells share many similarities with cancer cells such as ability to self-renew, unlimited proliferation and maintenance of the undifferentiated state. Embryo-cancer sequence A (ECSA), also known as developmental pluripotency associated-2 (DPPA2), is a cancer testis antigen (CTA) with unclear biological function yet. Objective: CTAs are expressed normal...
متن کاملGenic Expression Regulation in Microorganisms
region of the genes, denominated HAIR (HspR associated inverted repeat). For these studies we will construct a null mutant in gen CC0081, whose phenotype will be analyzed with respect to different kinds of environmental stresses. Another objective of this project deals with the characterization of 5 ECF (extracytoplasmic function) sigma factors from Caulobacter: SigF, SigU, SigT, SigE and SigR....
متن کاملA Mathematical Model for Cell Formation in CMS Using Sequence Data
Cell formation problem in Cellular Manufacturing System (CMS) design has derived the attention of researchers for more than three decades. However, use of sequence data for cell formation has been the least investigated area. Sequence data provides valuable information about the flow patterns of various jobs in a manufacturing system. This paper presents a new mathematical model to solve a cell...
