Can you expect to extract more DNA from a strawberry or kiwi fruit? Introduction: In the experiment we were inspecting the amount of genetic materials in fruits with different numbers of chromosomes. In the experiment‚ we mashed up a strawberry/kiwi fruit (See appendix 1 figure 2) added extraction butter and ethanol to extract the DNA. A chromosome is a long thread-like cluster of genes in the nucleus. DNA (deoxyribonucleic acid)‚ a self-replicating material which is present in nearly all living

With a new study on evolution‚ scientists have discovered that the mitochondrial genomes of birds have found two mutations within the mitochondrial genomes within fifty years. Within those fifty years it has shown two mutations within the mitochondrial genomes which can debunk the two percent of evolution per million years. By studying individual chickens Professor Greger Larson at Oxford University’s Research Laboratory for Archaeology‚ they have found two mutations in the mitochondrial genomes

Biochemical Prospective of DNA polymerase in Replication Biologists and chemists have long recognized a relationship among DNA‚ RNA‚ and protein‚ and this recognition has guided a vast amount of research over the past decades and generations. The pathway of DNA to RNA and RNA to protein is conserved in all forms of life and is often called the Central Dogma. DNA functions as a storage molecule‚ holding genetic information for the lifetime of a cellular organism‚ and allowing that information

INTRODUCTION: NULL HYPOTHEISIS: Mental disorders are not present in animals. HYPOTHESIS: As much as life has evolved‚ the relationship between animals and humans has remained very close to each other. If animals are‚ evolutionally‚ and genetically similar to humans; can they develop the same diseases we have today? Humans today

runs out of ways to identify human remains‚ DNA can play a key role in the identification process. The most common methods of identification by a forensic anthropologist include "detailed skeletal and dental features‚" of the remains‚ but they are sometimes asked to perform DNA profiles as well (Arismendi‚ Baker‚ & Matteson‚ 2004). According to the paper by Arismendi‚ Baker‚ and Matteson‚ when the common modes of identification do not yield any results‚ "DNA typing may provide a further avenue of investigation

Extraction and Analysis of Plasmid DNA from E. coli Cells Introduction A plasmid is an extra-chromosomal element‚ often a circular DNA. Since a plasmid is by definition an extra-chromosomal element‚ it cannot make use of any origin of DNA replication in a chromosome (BP site). Meaning that DNA synthesis within a plasmid depends on having an origin of DNA synthesis of its own. Plasmids are often found in bacterial cells‚ in which they are used as transfer agents for transmitting various antibiotic

following double-stranded DNA sequence: 5’-CAG AAG AAA ATT AAC ATG TAA-3’ 3’-GTC TTC TTT TAA TTG TAC ATT-5’ If the bottom strand serves as the template‚ what is the mRNA sequence produced by transcription of this DNA sequence and Why? 5’-CAG AAG AAA AUU AAC AUG UAA-3’ mRNA sequence 3’-GTC TTC TTT TAA TTG TAC ATT-5’ DNA template strand We get the mRNA sequence due the transcription process‚ which gives us the RNA bases that are complementary to the DNA template strand that uses

contributed to the discovery of the DNA. Frederick Griffith experiment was done in 1928‚ Oswald Avery’ was done during the early 1940’s‚ and Alfred Hershey’s with help from Martha Chase was done in 1952. All of these experiments contributed to the idea known as translation‚ the process of cell ribosomes converting proteins to messenger RNA‚ or mRNA. Because of how they helped with discovering translation‚ these three experiments help lead to the discovery of DNA. Before Frederick Griffith’s experiment

(the wilful killing of human being by another)‚ rape‚ aggravated assault‚ robbery and etc. All these incidents may solved with variety of trace and contact materials may to be found at a crime scene investigation such as blood and body fluids‚ fingerprints‚ footwear marks‚ all of which could provide intelligence information‚ to named suspects. Additional‚ evidential material in the form of paint‚ hairs‚ fibres‚ tool-marks and glass can also afford corroborative evidence to link suspect with crime

DNA Typing The discovery of the structure of DNA opened the realm of DNA technology and changed the way in which crimes can be solved. This is due to the fact that many criminals often unwittingly leave their DNA at crime scenes and/or the DNA of victims is carried away on the clothes of their assailants (Saferstein‚ 2015). Thus‚ by using DNA it is relatively easy to place individuals at crime scenes and discover key evidence. Before the 1980s‚ the courts primarily relied on testimony and eyewitness
