... Females have two X chromosomes and males only have one. When a boy is born, he takes one X chromosome from his mother and one Y chromosome from his father. Therefore, he can only get hemophilia through his mother. If there is a mother that is a carrier and has a daughter the gene could be passed do ...

Normal and aberrant SSCP products were isolated and sequenced by ABI PRISM 310 (PerkinElmer, Foster City, CA, U.S.A.). For the KCNQ1 gen ...

TRIPTYCHON and CAPRICE mediate lateral inhibition during

... In extensive screens for trichome patterning mutants to date, only one gene, the TRY gene, has been identi®ed that appears to function in lateral inhibition and hence most probably in cell±cell signalling (HuÈlskamp et al., 1994; Schnittger et al., 1998, 1999). To understand the molecular mechanism ...

Understanding the Scurred condition in Polled Cattle

... Most calves that are horned can be identified at birth or shortly after, and almost always by weaning time. Distinguishing between smooth-polled and scurred-polled is more difficult. Scurs, a rudimentary horn growth, are often not seen until cattle are nearly a year old or sometimes even older. Scur ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
