Title Application of DNA Barcodes to Identify Various Plant Species Abstract In this experiment we applied barcodes to plants in order to identify what species they are classified under. We also compared the DNA sequences of different plant species using the ribulose-biphosphate carboxylase gene (rbcL). We took samples from a plant called Chard and performed PCR‚ DNA amplification and quantification and sequenced the DNA. During the experiment‚ we hypothesized that this year’s “nonspinach”

instances of how our knowledge of DNA has changed life in our day. Give one positive and one negative application of that knowledge and defend your answer. According to Kenneth Saladin‚ deoxyribonucleic acid (DNA) is “a long threadlike molecule with a uniform diameter of 2mm‚ although its length varies greatly from the smallest to the largest chromosomes.” What does this mean? Basically‚ it is a long string that contains a person’s genetic information. DNA has been studied overtime and it

Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic information used in the development and function of all known living organisms and some viruses. It is a major macromolecule that is essential for all known forms of life. Knowing this‚ several groups of scientists raced to find out how this essential molecule was structured. In an attempt to answer this question‚ James Watson and Francis Crick got together at the Cavendish Laboratory in Cambridge‚ England to experiment and record

Associate Program Material DNA Worksheet Answer the following in at least 100 words: Describe the structure of DNA.DNA is thread formed by two strands‚ related together to form a double helix. The double helix looks like a twisted ladder. The sides of this ladder are long unites called nucleotides and are made of three parts; a nitrogenous base‚ a sugar‚ and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands of the DNA are attached by an appendage

Cell Transformation Cell transformation is when a cell takes in DNA from the outside of the cell. It then becomes a component of the cell’s DNA. There are three different ways in transforming the cells. There is transforming bacteria‚ transforming plant cells‚ and transforming animal cells. The purpose of cell transformation is to introduce a foreign plasmid in order to make large quantities of it. In transforming bacteria‚ a foreign DNA is first joined to a small circular DNA molecule known

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

Amy Tan and Maya Angelou come from extremely different cultures‚ and trying to feel accepted in American Culture. Both authors discuss a feeling of being an outcast and how their cultural differences set them apart. However‚ Amy Tan effectively uses narration and description to depict her sense of isolation from the dominant American culture. Angelou’s story is set in the South during the 1930’s when racism was prominent in society and an acceptable practice. Angelou’s writing mostly describes

In the Chinese culture now‚ their food and manners differ from Americans; Amy Tan shows the contrast of cultures in “Fish Cheeks”. Chinese New Year food and manners are different from the way we’re raised as Americans. The Chinese prepare food for the holidays that many of us haven’t even tried in our lifetime‚ yet they eat it more than once a year. During the dinner‚

Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic
