NOTE: It is not very crucial to read all of the context, though it would aid in understanding the reaction that is used in my investigation.
It would be recommended to at least read the abstract before going reading the investigation.

Software: Flash 8, Dreamweaver, FileZilla, Notepad, Adobe Photoshop

Idea Source: When I was working with a virologist at the Microbiology lab, I was following under his guidance, which was mainly on PCR (polymerase chain reaction) - it was sometime later in April that I wondered how the PCR would be affected by changing one of the reaction reagents.
Skills: HTML, how to use Flash, Photoshop, organization

Summary:

To express in very general terms, the focus of my project involves a reaction called PCR (polymerase chain reaction – further explained in context section). PCR is a reaction that reproduces vast quantities of DNA. I will specifically be using reverse-transcription real-time PCR (real-time PCR involves sophisticated equipment to detect product , reverse transcription is a step that converts RNA to DNA) to produce copies of a segment of the influenza virus (the matrix gene).
The main idea or objective is to change the concentration of one of the reagents - magnesium chloride.

I want to change the concentration or optimize the magnesium chloride concentration so that the PCR could produce products with efficiency.
How I will examine the efficiency is in terms of: 1. The initial amount of product formed in a given time (somewhat like speed - I am looking at the concentration that requires least number of cycles/time for product formation to occur) – This involves analyzing Ct values (the cycle number at which product forms). 2. How well PCR product formation adheres to the theoretical/expected exponential growth – This involves analyzing standard product-formation graphs.
