Technorati, Alexa and Google ranking

Technorati, Alexa and Google ranking of my blog are,
Technorati Rank - 1,930,801
Alexa Rank - still not availabla (Blogger.com has a traffic rank of: 9)
Google page Rank - 0/10
I'm finding ways to improve this. My blog is still not ranked by alexa. My blogs goole rank is 0. Overall ranks are very low. I'm searching google to find tips and tricks to improve page rankings.

DNA

DNA stands for Deoxyribonucleic acid. DNA contains the genetic instructions used in the development and functioning of all known living organisms. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information. DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. DNA is a long polymer made from repeating units called nucleotides. When a Base linked to a sugar is called a nucleoside. When a base linked to a sugar and to a phosphate group it is called as nucleotide.

Backbone of the DNA strand is made from alternating phosphate and sugar residues. The DNA double helix is stabilized by hydrogen bonds between the bases attached to the two strands. The four bases found in DNA are adenine, cytosine, guanine and thymine. Watson, Crick, and Wilkins jointly received the Nobel Prize for Discovering the structure of DNA molecule.

Genetically Engineered Cats & Dogs

Genetically engineered 'hypoallergenic' dogs may be available soon. So you should able to buy GM Pets on shops soon. Here is story about GM Cats. The major allergen in cats is the glycoprotein Fel d1 that is secreted by the sebaceous glands. This allergen is found in the fur, saliva, urine, mucous, salivary glands, and hair roots of the cat. This protein is produced by the Fel d1 gene. Scientists have developed a cat breed that produces a different version of the Fel d1 protein. According to Allerca, these cats no longer trigger the autoimmune system of people allergic to cats. The Allerca cats have been available since 2006. First scientists sought a method to delete or disable the gene. But in testing to see whether the gene had been effectively silenced, they made a fortuitous discovery: A very small number of cats carry a mutant gene that produces a modified protein, far less likely to induce allergies. At that point, the research shifted course. Allerca screened thousands of cats to identify a population with the modified gene and then set those cats to breeding. Because the mutant gene is dominant, the breeding cats could be mated with normal cats to produce hypoallergenic kittens.

By using proprietary genetic technology, ALLERCA manipulated naturally occurring genetic variations in cats, specifically targeting the gene Fel D1 that is responsible for the production of the common cat allergen. ALLERCA's technology detected genetic divergences consisting of minute variations in the code of the Fel D1 gene sequence.
