Introduction

Transcription：

The transcription stage, the reading of genetic information from DNA, is composed of promoter binding and the activation of RNA polymerase, RNA transcript initiation and promoter escape, RNA transcript elongation, and transcript termination, and release.

What is terminator?

Terminators are genetic parts that usually occur at the end of a gene or operon and cause transcription to stop. In prokaryotes, terminators usually fall into two categories (1) rho-independent terminators and (2) rho-dependent terminators.

Rho-independent terminators are generally composed of palindromic sequence that forms a stem loop rich in G-C base pairs followed by several T bases. The conventional model of transcriptional termination is that the stem loop causes RNA polymerase to pause and transcription of the poly-A tail causes the RNA:DNA duplex to unwind and dissociate from RNA polymerase.

The function of the software is brief that users only need to input the sequency of their terminator and then it can output the structure and efficiency of the terminator. For those users who can connect to the internet, we have our website www.terminatorefficiency.com for them to use without download our software, and for those who cannot, they can download our software to use.

Tools

Because we are a software producer, we need to use different tools to write our software. First, our algorithm were written using c# in vs2010, in order to get the aim that the software can run in the back of the user interface. Second, the software user interface was wrote in vs2010 using WPF directly which we thought is the easiest and most beautiful technology for windows software. The first and second version of the website was made by three software: Photoshop, which was used for getting great picture, Dreamwaver, which was used for making the structure of the interface, and vs2010, which was used for connecting the UI with our algorithm. When everything was done, we applied our own realm name and server to achieve the dream of building the website. Although the processes of debugging and building the server were very hard, we make our software successfully.
