DNA Replication DNA replication is a biological process that occurs in all living organisms and copies their DNA. The initiation of DNA replication starts with two steps. First an initiator protein unwinds a short stretch of the DNA double helix. Then a protein called helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands‚ pulling apart the two strands. DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule

Bioinformatics Leigh Ann Santana DNA Extraction Lab DNA extraction is an important process because the DNA first needs to be purified away from proteins and other cellular contaminants. Cell are needed‚ because that is where the DNA is located. Inside almost every cell in our bodies is a nucleus‚ and inside each nucleus is about two meters of DNA. The following steps are needed to purify DNA from a cheek swab. Collect cheek cells‚ Burst cells open to release DNA‚ separate DNA from proteins and debris

A DNA strand contains a complete representation of everything about our physiology. It also contains instructions on how to form our body by repeated divisions of a single cell. Each cell needs to know when it should‚ split into two‚ split into different kinds of cell for tissue differentiation. Cells also need to know when to stop growing because the body or organ is mature‚ and when it needs to replace tissue lost by injury. All of that is encoded into one molecule. So in other words the benefit

DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four

DNA Cloning PCB3063L Section DNA cloning refers to the process of making multiple copies of a DNA fragment. For the past weeks we have conducted a set of experiments that allow us to clone a specific gene in drosophila. First we started by the process of DNA extraction‚ which allowed us to isolate the genomic DNA from D. Melanogaster. This process requires the use of lysis in other to extract the DNA and RNA. After extracting the DNA‚ we it is important to use

DNA FINGERPRINTING Background Reading - Nelson Biology and Campbell Biology Purpose - To understand the basics of DNA fingerprinting used in the Canadian courts for crime convictions and paternity suits. Introduction The process of DNA fingerprinting was developed by Professor Alec Jeffreys at Leicester University in 1984 as a form of genetic analysis. It was first used in the law courts of England in 1987 to convict a man in a rape case. It has now been used successfully in many crime and paternity

Sherlock Holmes and Dr. Watson are both unique and intriguing characters. They have captured the imagination of all who have read any of Sir Arthur Conan Doyle’s detective stories. The adventures and crime solving are secondary to the characters and personality traits of Sherlock Holmes and Dr. Watson. The first thing to know about Sherlock Holmes is that he was an incredible detective. He could be very ambitious at times fully concentrating on solving a puzzling crime or he could be equally
