Table of Contents Introduction Restriction Fragment Length Polymorphism (RFLP) Polymerase Chain Reaction (PCR) Short Tandem Repeats (STR) References Introduction DNA profiling is an odd identification genetic passport that carries information about several dozen genome regions belonging to one person. DNA profiling analyzes the number of repeating elements in a selected area of the genome. The…

Organelles are a category of structures that constitute the cell within the organism. The most prominent one in eukaryotic cells is the nucleus, which contains the DNA and controls the cell’s operations. The mitochondria are primarily responsible for energy conversion, and the ribosomes produce proteins that are necessary for operations. The endoplasmic reticulum, which consists…

The incidence of malaria has been increasing at an alarming rate. Nearly 3000 million people are reported to be affected annually and 1/3 of them die. Confronting malaria has achieved good progress in the elimination of mosquito species that would carry Plasmodium parasites by eradiation of breeding grounds and using DDT (Crampton et al., 1992).…

Table of Contents History Current Event Conclusion References A study conducted at Paul Sabatier University found that societal shifts caused ancient hunter-gatherers to prefer male horses. The research used DNA from the remains of ancient horses to determine alterations in animal husbandry preferences. The study of DNA, starting with the human genome, has broadened to…

Short tandem repeat (STR) is a molecular biology tool mainly exploited in forensic science in order to determine certain locations known as loci present on the nuclear material, DNA. STR sites exhibit remarkable polymorphism which offers a reliable platform for forensic investigations to differentiate the DNA profiles from one individual to the other. STR DNA…

Table of Contents Introduction Main body Conclusion Reference List Introduction The evolutionary relationship between organisms has been measured and monitored using DNA and proteins from these organisms. This is because, members of the same species have the larger fraction of their genes (DNA) and proteins being common. Genes and products of genes (proteins) can be…

Table of Contents Introduction Methodology Mechanical Shearing Thermal Treatment DNA Precipitation Results Conclusion Introduction Physicochemical studies of key biological molecules are an essential part of laboratory practice to better understand their structure and identify possible patterns. The idea behind this work was to determine the viscosity of DNA molecules. It is well known that DNA…

When it is necessary to learn some physiological characteristics of human health conditions, scientists and researchers address genetic studies and focus on the peculiarities of the human genome. A number of nucleic acid sequences are encoded as deoxyribonucleic acid (DNA) to store the hereditary material. Almost every cell in the human body is coded by…

Table of Contents Mutation versus polymorphism Types of mutations Causes of mutations Somatic versus germline cells and clinical significance Importance of phenotypic mutations References Mutation versus polymorphism Although both mutations and polymorphism occur due to changes in DNA sequence, mutations are rare and lead to abnormal alleles. In other words, a mutation can best be…

The birth of molecular genetics has been significant in furthering the knowledge concerning the cell’s coding of information. Assuredly, the cell is responsible for carrying out specific functions in the body. Inside the cell is the nucleus, which contains the deoxyribonucleic acid accountable for carrying out the transcription and replication processes (Augustyn para. 1). Notably,…
