Understanding DNA

Understanding DNA - DNA is a nucleic acid that stores all the unique biological information of every living creature and some viruses. Its chemical structure of macromolecular complex consisting of three kinds of molecules, ie pentose sugar (deoxyribose), phosphoric acid, and a nitrogenous base. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. 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 genetic information.

Understanding DNA

DNA can replicate that form a copy of itself. Each strand of DNA containing a specific base sequences. Each base is also connected by sugar and phosphate molecules. When the bases form the rungs (horizontal), then the sugar and phosphate molecules forming the vertical part of the stairs.

DNA is short for deoxyribonucleic acid, or in Indonesian called deoxyribonucleic acid. DNA derived from the three main words that Deoxyribo, and nucleid acid (nucleic acid). Deoxyribo word meaning (Wikipedia) is a sugar loses its oxygen atom, while the meaning of the nucleic acid (Wikipedia) is a molecule that contains genetic information.

DNA molecules in our bodies are arranged in packets called chromosomes. Every human being has 23 pairs of chromosomes. One of the 23 pairs of chromosomes, called the sex chromosomes, are different in men and women. Females have two X chromosomes, men have chromosomes X and Y. Every organism has a different number of chromosomes. For example, simpanze have 24 pairs, 11 pairs bananas, and flies only 4 pairs.

Furthermore, the chromosomes are arranged in short segments of DNA called genes. When DNA is a recipe book, then each gene is a recipe. This recipe tells cells how to function and express certain properties. Humans have about 25,000 genes. Genes that determine hair color, hair type, skin color, eye color, etc. For example, a person has dark curly hair because the genes inherited from the parents instruct cells to form hair follicles and curly black hair.

Understanding Delusions

Understanding Delusions - Delusions are a hoax picture of observation, drawing all or gamabr who deceive us, with the evils that can not be corrected, and does not fit at all with the mind as well as his own opinion. Delusions were generally caused by past experiences are overwhelmed by feelings of sin and guilt, as well as haapan-expectations or not reached.

Understanding Delusions

Several types of delusions we may note here, is as follows:
1. Delusions hipokondris; No delusions always suffer pain patients feel bodily: accompanied chronic anxieties and fears about the health of the body's own patalogis. Patients feel "confident" it is true that he suffered from a serious illness. Each Simpton smallest pain was felt as a great disaster, which could mengakibatakan death. In particular this hipokondris delusions caused by a conflict with conflict intrapsychic long and severe.
2. nihilistic delusions: patients seized with feelings of "no longer exists or is dead". He felt like a worthless piece of dead bodies. Patients become desperate and useless life on earth.
3. Cotard syndrome: no delusion can not live anymore, which is accompanied by delusions could not possibly be dead. There was an idea she could no longer live in this world; but at the same time he felt confident could not possibly be dead. Therefore he constantly felt guilty to penetrate the sins and stains are attached to him, he must direjam with hell torments the world today.

Factors causing Delusions
Generally caused by pangalaman-pangalaman past overwhelmed by feelings of sin and guilt, as well as the expectations that have not been reached.

Understanding HTTP

Understanding HTTP

Understanding HTTP - HTTP stands for Hypertext Transfer Protocol is a protocol used to send documents or halamamn the WWW or World Wide Web. While understanding the big dictionary HTTP is a networking protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the WWW.

In terms of the HTTP, specify how messages are formatted and transmitted, and what the response of the browser. History of the HTTP protocol used in the WWW first time around 1990. Well used at that time is the HTTP protocol version 0.9 which is a data transfer protocol is raw, uncooked intent here is that data is sent regardless of the type of the document itself.

6 Years later, namely around 1996, the HTTP protocol has improved so that it becomes the HTTP protocol version 1.0. And in 1999 issued selanjjutnya ie HTTP version 1.1 to accommodate a proxy, caching and persistent connections.

HTTP is protoko simple client server based application that is built on TCP (transmission control protocol). An HTTP client typically initiates a request by creating a relationship to a particular port on a particular webhosting hserver sebua. Commonly used port is port 80. Clients also often known by the user agent, while the server responds and also save the resources such as HTML files and images is called the origin server.

Well between the two is the user agent and the origin server there may be oenghubung, such as geteway, tunnel and proxy. Well then the source you want to access by using HTTP are identified using a URL (Uniform Resource Locator) scheme URL http: or https :.

Function and How it Works HTTP

You must know that HTTP appears at the beginning of every web address. Yes all web services run through this protocol. HTTPS is a variant of HTTP in which case inibrowser add another layer of encryption.

The workings of this protocol is to communicate with one another. The protocol is the command to be followed by each computer to be able to send or receive messages. The use of the most common protocols are HTTP, SMTP, FTP, IMAP, POP3, and many others.

The function of the HTTP itself is to establish how the message or data that is formatted and ditrasmisikan into a form that could respond to the browser to bring these data.
