In the entry, I discuss how X-men in the comic book world differ from mutants in the real world. The processes are explained on a cellular level, building up, in order to show how a mutant can arise. This involves discussing how DNA works in the cell, and the various types of mutations that can be caused by mistakes in DNA.

Protein synthesis deals with the process of transcription and translation. The first step known as transcription involves dealing with the four DNA nucleotides (A, C, G, T). The DNA is then converted to mRNA which consists of A, C, G, U. The second step is known as translation, where the mRNA is translated into amino acids. The mRNA in translation step gets translated into tRNA.

Ribonucleic acids (RNA) are categorized into two separate classes. The two general classes of RNA are those that encode proteins (mRNA) and those that are functional as RNA (ncRNA). Functional RNA participates in multiple cellular processes including protein synthesis (tRNA, rRNA), RNA processing (snRNA), the regulation of gene expression (miRNA), and genome defense (siRNA, piRNA).

The polymerase chain reaction, PCR, is a scientific technique used to amplify a specific DNA sequence to produce millions of copies. Denaturing step:Samples are heated to 94– 96 degrees Celsius. The heat denatures the DNA by breaking the hydrogen bonds between the two DNA strands. Annealing step: primers form hydrogen bonds with their complementary sequences in the target DNA. Extension/elongation step:The thermo-stable DNA polymerase synthesizes a new DNA strand complementary to the DNA ...

Telomeres are located at the end of linear chromosomes. Shortening of telomeres is involved in cancer and aging. Telomerase somewhat prevents this process by elongating the telomeres. This article will discuss telomere structure and function, as well as how telomerase is involved in cancer and aging. Dysfunction of telomeres will also be discussed in their relation to premature aging, known as Werner ’s syndrome.

Everyone knows that Twins physically look alike, behave alike, and even have similar interests alike. Those are all stereotypes of twins, but people might not know that there are differences to them. Differences don't have to be always have to be a physical feature, they could be genetically different too.

This explains the general idea of population genetics and what is used in the field. Only two factors are explained for use to find variation in a population: single nucleotide polymorphisms and microsatellites. This only explains the significance of each factor for studying populations, nothing about how these factors are examine experimentally.

A brief overview of methods of transcriptional regulation in prokaryotic cells to control protein synthesis. Discussion of clustering of genes that produce related enzymes in a biochemical pathway into operons, and control of operons by repressors and allosteric effectors such as lactose. Simple description of of promoter binding of RNA polymerase and transcript synthesis.

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.

This article is about the structure of the DNA molecule and how it became to be. The article includes brief history of famous and Nobel Prize wining authors such as Rosalind Franklin, Maurice Wilkins, James Watson, James Watson, and Francis Crick. The article gives a small yet detailed information of the structure of DNA.

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.

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.
