FISH FISH stands for Fluorescence in situ hybridization. FISH is a technique in the lab used to see where a DNA sequence or certain gene is located in an individual’s genome. This allows scientists to look for genetic conditions caused by alterations in chromosomes. FISH can be used to find distinct features in DNA for genetic counseling‚ species identification‚ and medicine. It can also be used to find certain RNA points in cells and tissue samples. FISH is used on blood samples or any other cell

Related projects‚ often by scientific collaboration across continents‚ have generated the complete DNA sequences of many animal‚ plant‚ and microbial genomes. The first DNA sequences were obtained in the early 1970s by academic researchers using laborious methods based on two-dimensional chromatography. Following

specific DNA to be helpful in determining lineage. Within the mitochondria‚ numerous copies of DNA are found. The mitochondrial DNA is therefore more practical to use than the one copy in the traditional nucleus. The mitochondria itself has it’s own genome and has its own genes. The tiny organelle has a mere 37 genes that mainly remain unchanged (Rice University). According to Genebase‚ the mtDNA is also much smaller than nucleic DNA. Nucleic DNA ranges from 49‚530‚000 to 247‚200‚000 base pairs the

Vaccinations that act through different mechanisms provide methods of best containing viral spread. The significance that comes with vaccinations is understanding the herd mentality that medicine follows. In order to best protect a large population‚ it is not necessary‚ and is nearly impossible‚ to vaccinate all members of that community. However‚ vaccinations still prove to be effective methods of preventing diseases. This occurs by ensuring that an infected person is most likely to come into contact

of the cell-free DNA floating in a pregnant woman’s blood stream stems from her fetus. In 2010 in a paper published in Science Translational Medicine‚ Lo’s group showed that enough fragments of fetal DNA are there to reconstruct the fetus’s whole genome‚ and it should be possible to use this DNA to test the unborn child for genetic diseases without exposing it to the risk of an invasive procedure. One strategy makes use of subtle genetic variations that exist between a mother’s pairs of chromosomes

Systems Biology Systems biology involves the study of an organism as one single system. Instead of analysing all the individual components that make up a cell‚ the cell is instead viewed as an interacting network of genes‚ proteins and biochemical reactions and these are studied as a whole. In 20th century‚ molecular biology was focused upon. A ‘reductionist’ approach was followed‚ in which the individual components‚ such as the cell nucleus or sugar metabolism‚ were studied in isolation. However

The human genome comprises a sequence of approximately 3 billion component parts‚ called nucleotides‚ which are organized into DNA molecules—the double helix. The nucleotides‚ which serve as the alphabet for the language of life‚ are represented by just four
