Dow Jones Industrial Index Clone Shooting Star Doji Candlestick Pattern

Giant hanging man followed by tiny clone shooting star doji candlestick charting pattern. Expect a drop towards the green dotted line support at 12765. If this support hold does not hold the next support is at the mid Bolinger Band at 12640. Conversely, if the unexpected happens the index will propel towards the upper resistance line of the raising wedge and test the 13000 mark.

Broke blue uptrend support line during early morning trading and attempted to rebound back above this support line but failed and continue to drop to intraday low of $3.05 . Next support is the red downtrend resistance turned support line. Breakdown below $3.04 to $3.00 support band will retest next support at $2.94 . Immediate resistance is the support band $3.15 to $3.13 followed by 20 EMA resistance line.

Option (finance)

Options are financial instruments that convey the right, but not the obligation, to engage in a future transaction on some underlying security, or in a futures contract. In other words, the holder does not have to exercise this right, unlike a forward or future. For example, buying a call option provides the right to buy a specified quantity of a security at a set strike price at some time on or before expiration, while buying a put option provides the right to sell. Upon the option holder's choice to exercise the option, the party who sold, or wrote, the option must fulfill the terms of the contract.[1][2]

The theoretical value of an option can be determined by a variety of techniques. These models, which are developed by quantitative analysts, can also predict how the value of the option will change in the face of changing conditions. Hence, the risks associated with trading and owning options can be understood and managed with some degree of precision.

Exchange-traded options form an important class of options which have standardized contract features and trade on public exchanges, facilitating trading among independent parties. Over-the-counter options are traded between private parties, often well-capitalized institutions, that have negotiated separate trading and clearing arrangements with each other. Another important class of options, particularly in the U.S., are employee stock options, which are awarded by a company to their employees as a form of incentive compensation.

Other types of options exist in many financial contracts, for example real estate options are often used to assemble large parcels of land, and prepayment options are usually included in mortgage loans. However, many of the valuation and risk management principles apply across all financial options.


The World of Nanotechnology

Experts sometimes disagree about what constitutes the nanoscale, but in general, you can think of nanotechnology dealing with anything measuring between 1 and 100 nm. Larger than that is the microscale, and smaller than that is the atomic scale.

Nanotechnology is rapidly becoming an interdisciplinary field. Biologists, chemists, physicists and engineers are all involved in the study of substances at the nanoscale. Dr. Störmer hopes that the different disciplines develop a common language and communicate with one another [source: Störmer]. Only then, he says, can we effectively teach nanoscience since you can't understand the world of nanotechnology without a solid background in multiple sciences.

One of the exciting and challenging aspects of the nanoscale is the role that quantum mechanics plays in it. The rules of quantum mechanics are very different from classical physics, which means that the behavior of substances at the nanoscale can sometimes contradict common sense by behaving erratically. You can't walk up to a wall and immediately teleport to the other side of it, but at the nanoscale an electron can -- it's called electron tunneling. Substances that are insulators, meaning they can't carry an electric charge, in bulk form might become semiconductors when reduced to the nanoscale. Melting points can change due to an increase in surface area. Much of nanoscience requires that you forget what you know and start learning all over again.

So what does this all mean? Right now, it means that scientists are experimenting with substances at the nanoscale to learn about their properties and how we might be able to take advantage of them in various applications. Engineers are trying to use nano-size wires to create smaller, more powerful microprocessors. Doctors are searching for ways to use nanoparticles in medical applications. Still, we've got a long way to go before nanotechnology dominates the technology and medical markets.


Messenger RNA (mRNA) and Transfer RNA (tRNA)

Messenger RNA (mRNA) carries information about a protein sequence to the ribosomes, the protein synthesis factories in the cell. It is coded so that every three nucleotides (a codon) correspond to one amino acid. In eukaryotic cells, once precursor mRNA (pre-mRNA) has been transcribed from DNA, it is processed to mature mRNA. This removes its introns—non-coding sections of the pre-mRNA. The mRNA is then exported from the nucleus to the cytoplasm, where it is bound to ribosomes and translated into its corresponding protein form with the help of tRNA. In prokaryotic cells, which do not have nucleus and cytoplasm compartments, mRNA can bind to ribosomes while it is being transcribed from DNA. After a certain amount of time the message degrades into its component nucleotides with the assistance of ribonucleases.

Transfer RNA (tRNA) is a small RNA chain of about 80 nucleotides that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. It has sites for amino acid attachment and an anticodon region for codon recognition that binds to a specific sequence on the messenger RNA chain through hydrogen bonding.


Functions for Some Subsets of Junk DNA

  • A 2002 study from the University of Michigan showed that segments of junk DNA called LINE-1 elements, once thought to be "leftovers from the distant evolutionary past" now "deserve more respect" because they are capable of repairing broken strands of DNA. [18]
  • A 2003 study from Tel Aviv University found crucial uses for "junk" sequences in human DNA. [3]
  • A 2004 study from the Cell Press suggests that "more than one third of the mouse and human genomes, previously thought to be non-functional, may play some role in the regulation of gene expression and promotion of genetic diversity." [4]
  • An article from BioEd Online details DNA which appears crucial although no function has yet been discovered. [5]
  • A 2005 study from the National Institutes of Health found that social behavior in rodents (and, possibly humans [6]) was affected by portions of the genetic code once thought to be "junk." [7]
  • A 2005 study from University of California-San Diego suggested that junk DNA is "critically important to an organism’s evolutionary survival." [8]
  • Findings from Purdue University in 2005 stated that "many DNA sequences previously believed to have no function actually may play specialized roles in cell behavior." [9]
  • A 2006 study by the McKusick-Nathans Institute of Genetic Medicine (Johns Hopkins) stated that "Junk DNA may not be so junky after all." [10]
  • Researchers at the University of Illinois Society for Experimental Biology found an antifreeze-protein gene in a species of fish which "evolved" from junk DNA. [11]
  • A mathematical analysis of the genetic code by IBM identified patterns that suggested junk DNA had an important role after all. [12]
  • In 2006, University of Iowa researchers documented segments of RNA (previously considered "junk") that regulated protein production, and could generate microRNAs. [13]
A 2007 study from Stanford University School of Medicine found that "Large swaths of garbled human DNA once dismissed as junk appear to contain some valuable sections."
