DNA is found in all living organisms. It contains genetic codes which regulate the production of proteins and most importantly the activity of enzymes within a cell. Enzymes are extremely necessary for the cell to make other molecules essential for life. DNA is also responsible for passing traits from one cell generation to the next which allows organisms to function properly and to adapt over time.

This article is about transcription, and the differences that are present in eukaryotes and prokaryotes. It includes initiation of transcription, termination of transcription, and how prokaryotes and eukaryotes are different from each other in those aspects. It also covers how the nucleus is a major part of the difference between the two, and probably the main reason there are so many differences. It also covers some brief history on the matter, and why itÂ’s important to learn.

After reading this you should understand all aspects of Sanger Sequencing. You will understand what components are used and the method used to sequence DNA. You will also understand what a ddNTP is and how to read the polyacrylamide gel. Finally you will understand how Sanger Sequencing is so important for genetics.

Although DNA is now regarded as the genetic material for organisms, at one point in time it was hotly contested. For instance, some scientists at the time believed that proteins were the source of genetic material due to the fact that they composed of 20 amino acids versus the 4 nucleotides that make up DNA and could therefore code for more information. However several experiments helped prove that DNA was indeed genetic material necessary for life.

Epigenes are a source of inheritance from environmental, diet and lifestyles passed on from generation to generation. What a person does earlier in their life or may be exposed to can completely change the way that certain genes are expressed and may even cause diseases such as obesity or even cancer.

This article is a description of the experiment performed by Frederick Griffith and its influence on how DNA is now viewed. Up until the Griffith experiment as well as other experiments and the findings of Watson and Crick in the early 20th century DNA was not known to be the carrier of all genetic material instead it was thought to be proteins. However, through a series of experiments the true value of DNA was finally discovered.

The article presents a quick overview of the general operon. The operon is detailed structurally and generalized functionally. The purpose is to give readers a quick summary of the structure and function of each structure that regulate operon function. Also the type of regulation, (positive/ negative), are tapped into which help create an image of how the operon is regulated and it's functionality due to that regulation.

Overviews bacteriophage as a nonliving virus relying on their host to compose multiple copies of their biosynthetic machinery. Reviewing the debate of who proclaimed the true discovery of bacteriophage due to the publications of their independent discoveries. Summarizes the structure and lytic life cycle of the virus and how this function acts as a model organism for scientists working in the labs.

Most individuals studying Genetics find themselves confusing the many different kinds of RNA with each other. The following is a breakdown of the different kinds of RNA and their functions. First a brief background of RNA:a ribonucleic acid, and an essential part of processes such as protein synthesis. RNA is made up of nucleotides that are made up of a ribose sugar, a phosphate group, and a base(A,C,G,U).

Alcohol can shut down motor skills in organism leading to sedation. The exposure to ethanol vapors in Drosophila proves that when an organisms becomes induced in alcohol movement decreases. Initially alcohol causes a startling response but over time decreases locomotion. The patterns of alcohol exposure to flies can be correlated to humans.

This article describes the basics of biologyÂ’s central dogma: DNA to RNA to Protein. It includes the processes of transcription of a DNA gene segment into a messenger RNA molecule and the process of translating that mRNA molecule into its corresponding protein. This article also includes regulations of the processes and important proteins responsible for their entire completions.
