Strawberries
Strawberries are small delicate fruit. They can range from having a cone shape, to a spherical shape. They are red juicy fruits thats seeds grow on the outside. They can average about 200 seeds on them and are the only fruits that have their seeds on their skin. Strawberries are the first fruit to ripen in the spring. Strawberries are part of the rose family and are part of the plantae family. Strawberries can usually prevent heart attacksStrawberries grow on plants that can yield strawberries for more 5 years if its healthy and isn’t attacked by insects. They were thought to get their name when the farmers put straws around them for protection earning the strawberry name. Strawberries also contain 90% water. They grow on low growing plants that grow white flowers that later become strawberries. The main plant can send out runners that can form a new plant and grow more strawberries. Strawberries usually grow 12 weeks after planted. The strawberry plant needs insects to pollinate their flowers. When eaten strawberries can give you vitamin C, iron and other minerals.It contains 18mg potassium and gives people 4 calories. In Italy they were first grown in 234 B.C. The first strawberries were found in Virginia by Europeans in 1588. Then in 1860 framers in America started planting them.But the first strawberries where picked in the forests and in ancient rome was used to make medicine. Strawberries are usually planted using the plasticulture method. This method is when people build large beds of soil and cover them with plastic and adding seeds and making holes so the seed can grow. The plastic will prevent weeds and erosion. In the beds they would implant tubes that export water to the strawberries. Framers pick straw...

...ates. Dish detergent is a thick liquid that can have antibacterial properties. They were made in 1916 when soap was not used as much for cleaning.
Cells
Cells are the things that hold the DNA. Every living organism contains at least one cell. They are sometimes known as the building blocks of life. Cells were discovered in 1839 by Schleiden and Schwann.
The Science Behind the Project
In the project you isolate DNA from strawberries. When you mash the strawberries you get the DNA into a solution. The solution of salt and dish detergent bust open the cells to release the DNA so its easier to get the DNA. When you pour it in the cup you filter the clunks of the strawberries and get the solution and the material that contain the cells. So to separate the DNA you add the alcohol it precipitates. The DNA will fall out of the cells. The DNA can be used to be analyzed.
samples. In our experiment we learned the how to replicate tiny samples of DNA into usable
DNA is the genetic material found in cells of all living organisms. Human beings contain approximately one trillion cells (Aronson 9). DNA is a long strand in the shape of a double helix made up of small building blocks (Riley). The repeat segments are cut out of the DNA strand by a restrictive enzyme that acts like scissors and the resulting fragments are sorted out by electrophoresis (Saferstein 391).
Many things have impacted both the Science and Medical fields of study. Electrophoresis and DNA Sequencing are two of these things. Together they have simultaneously impacted both of these fields. On one hand, there is Electrophoresis. Electrophoresis is a specific method of separating molecules by their size through the application of an electric field. It causes molecules to migrate at a rate and distance dependent on their size. On the other hand, there is DNA Sequencing. DNA Sequencing is a technique used to determine the exact sequence of bases
DNA (Deoxyribonucleic acid) is a molecule found in in the nucleus of all cells in the body which carries our genetic information. DNA is found in the form of chromosomes, with a total of 23 pairs in the human body1. DNA holds the genetic coding for all our characteristics, i.e. our eye colour, body shape, and how we interact with others on a daily basis.

The cell is the most basic unit of life, defined as “The fundamental ... structural and functional unit of all living organisms” (Oed.com, 2013). The prokaryotic cell is typically composed of a plasma membrane and cell wall, containing within it the cytosol and a structure known as the nucleoid. This is a single piece of circular or linear DNA that floats freely in the cytosol of the cell (Thanbichler et al., 2005, pp. 507).
DNA analysis is a scientific process among the newest and most sophisicated of techniques used to test for genetic disorders, which involves direct examination of the DNA molecule itself (Lyman, 2014) . Today crime labs use mtDNA analysis. This type of analysis allows smaller degraded pieces of DNA to still be successfully tested (Lyman, 2014) . There are several steps taken when analyzing DNA in forensics. When testing scientists must first isolate the DNA so it is not contaminated and can't be used. Lab technicians the take small pieces of the DNA, conserving as much as they can encase they need to test again. Once testing is done the next step is determining the DNA test results and finally there is the comparison and interpretation of the test results from the unknown and known samples to determ...
... have been doing a phenomenal job of figuring this out. DNA is the chemical in each cell that carries our genes. DNA is the source of just about everything. It not only determines what we look like, but also many other things. Instructions are on some of our genes to let them know when they need to multiply and divide. Cancers can be caused by DNA defects.
The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm, the composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid (DNA), containing coded instructions for the behavior and reproduction of the cell and also the chemical machinery for the translation of these instructions into the manufacture of proteins. Viruses are not considered cells because they lack this translation machinery; they must parasitize cells in order to translate their own genetic code and reproduce themselves.
Detergent comes from the Latin word detergere meaning to clean, it is defined as a cleansing agent. Therefore, water itself is a detergent. This essay looks at soap and soapless (or synthetic) detergents. Both substances we use everyday and have a big market commercially, they effect everyone. Soaps are made from natural products and soapless detergents are produced chemically, each having advantages and disadvantages.
LAB REPORT 1st Experiment done in class Introduction: Agarose gel electrophoresis separates molecules by their size, shape, and charge. Biomolecules such as DNA, RNA and proteins, are some examples. Buffered samples such as glycerol and glucose are loaded into a gel. An electrical current is placed across the gel.
In our experiments we went to look how cells function and what are their features. In finding this information, I know have a better understanding of how cells function and their specific features.
The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
As seen on many crime shows and at real-life crime scenes, it is necessary to be able to identify DNA. Most of the time, this is done using a technique known as gel electrophoresis. Gel electrophoresis is a method used to separate the macromolecules that make up nucleic acids, such as DNA and RNA, along with proteins. Gel electrophoresis is significant because it has given scientists insight on what cells cause certain diseases and has led to advancements in DNA and fingerprint identification. My experiment will use gel electrophoresis to compare samples of natural and synthetic food dyes. The background for this experiment broaches the following subjects: inventors, real-world uses, necessary components, separation, and information on food dyes.
The scientific and medical progress of DNA as been emense, from involving the identification of our genes that trigger major diseases or the creation and manufacture of drugs to treat these diseases. DNA has many significant uses to society, health and culture of today. One important area of DNA research is that used for genetic and medical research. Our abi...
