What's Prototypes for JavaScript?

Objects have "prototypes" from which they may inherit fields and functions.

<script type="text/javascript">
function movieToString() {
return("title: "+this.title+" director: "+this.director);
}
function movie(title, director) {
this.title = title;
this.director = director || "unknown"; //if null assign to "unknown"
this.toString = movieToString; //assign function to this method pointer
}
movie.prototype.isComedy = false; //add a field to the movie's prototype
var officeSpace = new movie("OfficeSpace");
var narnia = new movie("Narni","Andrew Adamson");
document.write(narnia.toString());
document.write("
Narnia a comedy? "+narnia.isComedy);
officeSpace.isComedy = true; //override the default just for this object
document.write("
Office Space a comedy? "+officeSpace.isComedy);
</script>

What is a recombinant DNA organism?

Recombinant Antibody
The term recombinant and especially recombinant DNA regards to an artificial methods of producing DNA (synthetic DNA and proteins).

The manufacturing technique make use of bacterias, these bacterias are genetically modified in such a way that a specific DNA segment (gene) is artificially combined with their original DNA. After this insertion of DNA segment. The bacterias are nourished and kept in ideal conditions for reproduction and after a relative short period of time, after the reproduction, these specific segment of DNA is extracted out of the original DNA bacterias.

In short a segment of DNA is recombined (recombinant) with the original DNA of the bacteria, these genetically modified bacterias are rapidly reproduce and by that reproduce the DNA segment that was recombined with the original genome.

Antibodies are protein molecules produced by our immune system, the shape of an antibody is similar to a Y shape. The role of the antibodies to keep our health is crucial, their task is to recognize and attack foreign bacterias and viruses in our body.

There are many types of antibodies, each type can recognize unique antigen, the antibody Y tips has a unique molecular structure (keys) that combines with the targeted antigen. This attachment of many antibodies to a foreign objects (bacteria or virus) ultimately brings to its destruction.

Using recombinant antibody has significant advantages compared with the conventional antibody and there for its use becoming more popular now days. The fact that no animals are needed in the manufacturing procedure of the recombinant antibodies, in addition, the manufacturing time is relatively short compared with the conventional method. Moreover, the quality of the final product is higher that these of the non recombinant method.

IT Interview Questions:What is ARP?

What is ARP Cache Poisoning?
Address Resolution Protocol (ARP) is a protocol
for mapping an Internet Protocol address (IP address) to a physical machine
address that is recognized in the local network. For example, in IP Version
4, the most common level of IP in use today, an address is 32 bits long. In
an Ethernet local area network, however, addresses for attached devices are
48 bits long. (The physical machine address is also known as a Media Access
Control or MAC address.) A table, usually called the ARP cache, is used to
maintain a correlation between each MAC address and its corresponding IP
address. ARP provides the protocol rules for making this correlation and
providing address conversion in both directions.
