RANELLE JANINE L. ASI BIO 120 S-5L EXERCISE 9. Genomic DNA Isolation & Exercise 10. Polymerase Chain Reaction (PCR) Cell and molecular biology is a science based on the various systems of a cell resulting to its regulation‚ maintenance and function. Many of these systems involve genetic information hence the study of the DNA is an essential part of this field. To able to analyze DNA‚ it must first be isolated and purified from its natural environment filled with biological molecules and compounds

Introduction Cancer‚ when you read that word what goes through your head? Many of us know someone who has been diagnosed with this terrible disease. It is one of those diagnoses where you just don’t know what is going to happen. It can be very unpredictable‚ however there are many more cases where those who were diagnosed go into remission. Cancer is so hard to treat because the tumor cells are constantly growing and mutating. The tumor itself is a mutation of our own cells and since it is an ever

double stranded DNA ¡VdsDNA). The DNA of the phage contains around 50‚000 base pairs and codes for 50 proteins. At both ends of the DNA of the phage‚ there are cohesive ends‚ which are composed of 12 nucleotides. Both ends compliment each other‚ which makes the DNA circular once together. This circular DNA is usually present in an infected bacterial cell. This protects the DNA to be degraded by the cell. In this laboratory experiment‚ restriction enzymes were used to analyze the DNA of the lambda

EXPERIMENT NO.1 TITLE : EXTRACTION OF DNA DATE & DAY : 24 JUNE 2014 TITLE: EXTRACTION OF DNA OBJECTIVE: Extract DNA from yeast‚ onion and apple. INTRODUCTION: Every cells of living organism contains genetic materials known as deoxyribonucleic acid‚ DNA. It can be isolated from tissue sample of living things by separating it from other cellular component in a manner that still preserves its structures. The structure of DNA is double-stranded helices that made up

Premium DNA Gene
technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude‚ generating thousands to millions of copies of a particular DNA sequence. Developed in 1983 by Kary Mullis‚[1][2] PCR is now a common and often indispensable technique used in medical and biological research labs for a variety of applications.[3][4] These include DNA cloning for sequencing‚ DNA-based phylogeny‚ or functional analysis of genes; the diagnosis of hereditary diseases;
