Light Crude Oil Measured Move Projection

Using measured move projection as shown in the chart above the price of Light Crude Oil will probably hit $125 around the second week of May 2008. Price has just moved from the lower uptrend channel into the mid channel . Expect a move to the higher channel if demand continues to outstrip supply.

Yangjiziang Testing Previous Peak and 50 days EMA

Testing previous peak at $1.05 and 50 days EMA resistance line are imminent. Clearing these 2 resistances will propel price to challenge next resistance at $1.20 . Immediate support is the 20 days EMA support line followed by lower uptrend channel support line.

DNA Microarrays - A technology that is reshaping molecular biology

It is widely believed that thousands of genes and their products (i.e., RNA and proteins) in a given living organism function in a complicated and orchestrated way that creates the mystery of life. However, traditional methods in molecular biology generally work on a "one gene in one experiment" basis, which means that the throughput is very limited and the "whole picture" of gene function is hard to obtain. In the past several years, a new technology, called DNA microarray, has attracted tremendous interests among biologists. This technology promises to monitor the whole genome on a single chip so that researchers can have a better picture of the interactions among thousands of genes simultaneously.

Terminologies that have been used in the literature to describe this technology include, but not limited to: biochip, DNA chip, DNA microarray, and gene array. Affymetrix, Inc. owns a registered trademark, GeneChip®, which refers to its high density, oligonucleotide-based DNA arrays. However, in some articles appeared in professional journals, popular magazines, and the WWW the term "gene chip(s)" has been used as a general terminology that refers to the microarray technology. Affymetrix strongly opposes such usage of the term "gene chip(s)". More recently, I prefer the term "genome chip", indicating that this technology is meant to monitor the whole genome on a single chip. GenomeChip would also include the increasingly important and feasible protein chip technology.

The Double Helix

To understand the significance of what GeneChip expression analysis microarrays do, you need to understand the basics of DNA. DNA is a long chain of molecules shaped like a double helix, or a very long spiral staircase. DNA is the genetic blue print, or script, providing instructions for all cellular processes.

Whereas DNA is the script for making ribonucleic acid (RNA) and proteins, RNA directs the production of all proteins including enzymes and the structural proteins that make up our ears, liver, heart, hair and skin.

MICROARRAYS: CHIPPING AWAY AT THE MYSTERIES OF SCIENCE AND MEDICINE

With only a few exceptions, every cell of the body contains a full set of chromosomes and identical genes. Only a fraction of these genes are turned on, however, and it is the subset that is "expressed" that confers unique properties to each cell type. "Gene expression" is the term used to describe the transcription of the information contained within the DNA, the repository of genetic information, into messenger RNA (mRNA) molecules that are then translated into the proteins that perform most of the critical functions of cells. Scientists study the kinds and amounts of mRNA produced by a cell to learn which genes are expressed, which in turn provides insights into how the cell responds to its changing needs. Gene expression is a highly complex and tightly regulated process that allows a cell to respond dynamically both to environmental stimuli and to its own changing needs. This mechanism acts as both an "on/off" switch to control which genes are expressed in a cell as well as a "volume control" that increases or decreases the level of expression of particular genes as necessary.

What is a gene?

A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes.

Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Genes are made up of DNA. Each chromosome contains many genes.

DNA Major and minor grooves

The double helix is a right-handed spiral. As the DNA strands wind around each other, they leave gaps between each set of phosphate backbones, revealing the sides of the bases inside (see animation). There are two of these grooves twisting around the surface of the double helix: one groove, the major groove, is 22 Å wide and the other, the minor groove, is 12 Å wide.^[10] The narrowness of the minor groove means that the edges of the bases are more accessible in the major groove. As a result, proteins like transcription factors that can bind to specific sequences in double-stranded DNA usually make contacts to the sides of the bases exposed in the major groove.
