http://onscience.blogspot.com/2006/11/british-soldiers-kill-white-rhino.html
A boom for all scientists. Sunday, November 19, 2006. British soldiers kill white rhino. British troops training in northern Kenya have shot dead a white rhinoceros after it charged at them. The four soldiers were confronted by the adult male after they got lost at night on an exercise in the bush. The shooting happened on Friday evening in Laikipia, north of the capital Nairobi. The area is popular for wildlife viewing. Subscribe to: Post Comments (Atom). To manage your photos, please . Sharp Eye on the...

The only difference between people (or any animal) is the order of the base pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence. How is DNA Fingerprinting Done? 1 Performing Sourthen Blot. 1 Isolating the DNA in question from the rest of the cellular material in the nucleus. This...

E = MC2: What is DNA ?
http://onscience.blogspot.com/2006/11/what-is-dna.html
A boom for all scientists. Tuesday, November 21, 2006. 1 Nucleotides are the building stones of DNA. There are 4 different nucleotides :. DATP : deoxyadenosine triphosphate. DGTP : deoxyguanosine triphosphate. DTTP : deoxythymidine triphosphate. DCTP : deoxycytidine triphosphate. For convenience, these 4 nucleotides are called dNTP's (deoxynucleoside triphosphates). A nucleotide is made of three major parts : a nitrogen base. Molecule and a triphosphate. 2 How do the nucleotides form a DNA chain? The Pri...

E = MC2: Sharp Eye on the Sun

A boom for all scientists. Sunday, November 19, 2006. Sharp Eye on the Sun. The sun is hotter than anything you can probably imagine, but that may not be the most striking thing about our closest star. The real surprise is that the sun's thin outer atmosphere, or corona, is much, much hotter than the sun's surface. That's like the air high above a flame being hotter than the flame itself. The temperature should fall as you move away from a heat source. Hinode's X-ray telescope can record emissions that r...

http://onscience.blogspot.com/2006/11/what-is-dna-sequence-alignment.html
A boom for all scientists. Tuesday, November 21, 2006. What is DNA Sequence Alignment? To compare two or more sequences, it is necessary to align the. Residues across all the sequences (identification of locations of insertions and deletions that have occurred since the divergence of a common ancestor). These residues form a pattern. The bases match : this means that there is no change since their divergence. The bases mismatch : this means that there is a substitution since their divergence. D = y sum(w.

Researchers at the University of Michigan announced the testing of a drug delivery system that involves drug-toting nanoparticles and a guiding peptide to target cancerous cells in the brain. Their study finds that via this method more of the drug can be delivered to a tumor's general vicinity. They report their findings in the November 15 issue of. A small bio...

E = MC2: The Principle of DNA Sequencing
http://onscience.blogspot.com/2006/11/principle-of-dna-sequencing.html
A boom for all scientists. Tuesday, November 21, 2006. The Principle of DNA Sequencing. The purpose of sequencing is to determine the order of the nucleotides of a gene. For sequencing, we don't start from gDNA (like in PCR) but mostly from PCR fragments or cloned genes. The sequencing reaction :. There are three major steps in a sequencing reaction (like in PCR), which are repeated for 30 or 40 cycles. At 94°C :. At 50°C :. At 60°C :. Animated picture of sequencing (344 kB). Separation of the molecules :.
