Chromosomal Evolution Advancement In Sea Cradles
2012-12-12 15:45:38

Pensoft Publishers The study of chromosome changes arisen during species evolution is a current and intriguing topic that evolutionary biology proposes. However, in several groups (for example, mollusks), and chitons in particular, chromosome studies are scarce, with a few species investigated and analyses performed mostly with simple methods. Only 2,5% of about 900 living species of chitons have been so far karyologically investigated, all of them in the same order (Chitonida). The...

Genetic Test Reveals More About Potential Birth Defects Than Conventional Methods
2012-12-06 11:43:12

Lawrence LeBlond for redOrbit.com - Your Universe Online Two new papers published in the New England Journal of Medicine (NEJM) show that genetic testing in early pregnancy reveals far more about potential birth defects and stillbirth risk than current prenatal testing does, based on a multi-center clinical trial using both methods. The clinical trials showed that 6 percent of certain fetuses declared normal by conventional prenatal tests were found to have genetic abnormalities using...

Plant Chromosome Number Variation From Mediterranean Coasts To Tatra Mountains And Beyond
2012-11-27 15:37:25

Pensoft Publishers Chromosome number is the most basic feature concerning the genome of a species, and it is known for about one third of higher plant species. In particular, for plants of Italy, Slovakia, and Poland, online chromosome number databases have been developed: 'Chrobase.it — Chromosome numbers for the Italian flora', 'Karyological database of ferns and flowering plants of Slovakia' and 'Chromosome number database — PLANTS', respectively. The three datasets account...

Down Syndrome Researchers Remove Extra Chromosome

Brett Smith for redOrbit.com - Your Universe Online Geneticists from the University of Washington won a key victory in the battle against genetic diseases by successfully removing the extra chromosome 21 from cells derived from a person with Down syndrome, according to the team´s report in the journal Cell Stem Cell. Down syndrome, also known as trisomy 21, is caused by an extra copy of chromosome 21. In addition to the tell-tale facial features such as an abnormally small chin and...
