I want to become a doctor because I have a deep desire to help others and make a positive impact on their lives. Medicine is a field that allows me to do this in a meaningful and impactful way.
As a child, I was always fascinated by science and how the human body works. I would spend hours reading about different diseases and conditions, and I always had a strong curiosity about how doctors were able to diagnose and treat these issues. As I grew older, this fascination only deepened, and I knew that I wanted to pursue a career in the medical field.
But it wasn't just my love of science that led me to this decision. I have always been a compassionate and empathetic person, and I feel a strong sense of responsibility to use my skills and abilities to help others. I believe that being a doctor is the perfect way for me to do this.
In order to become a doctor, I know that I will need to work hard and commit to many years of education and training. I am prepared for this challenge, and I am confident that with hard work and dedication, I can achieve my dream of becoming a physician.
I am excited to enter this rewarding and challenging field, and I am eager to make a difference in the lives of my patients. Becoming a doctor will allow me to use my knowledge and skills to improve the health and well-being of others, and that is a truly rewarding and fulfilling career path for me.
DNA extraction from strawberry fruit report
The assertion implies that DNA with short strands runs a longer distance along the gel while the DNA with longer strands runs a shorter distance through the gel. Background Information DNA is in all living things, and stores all of the genetic information. After incubation, the tubes were micro-centrifuged for 5 minutes at 12000 rpm so that the precipitated DNA could settle at the bottom. British Food Journal, 106 9 , pp-678. The solution was mostly clear, but a little frothy and yellow from the soap.

Strawberry DNA Extraction Lab Revised
Which do you predict will yield a greater quantity of DNA—5 g of strawberry tissue or 5 g of banana tissue? The results obtained in this experiment are only applicable when the reagents and conditions are maintained. Next, we filtered our It filtered very slowly because our mixture was so thick. This simple strawberry DNA extraction lab is a cool lesson in how so many of the living organisms on this planet are made up of DNA! This extraction buffer will help provide us access to the DNA inside the cells. Experimental Procedure Equipment and materials used in the experiment were as follows: 1 resealable plastic bag 3-4 per student strawberries fresh or frozen 2 teaspoons dish detergent 1 teaspoons salt ½ cup water 2 beakers or plastic cups one cup will be used for the filtering equipment below filtering equipment: coffee filter and plastic cup ice cold 90% rubbing alcohol 1 wooden popsicle stick or plastic coffee stirrer. Sometimes it looks like many small pieces of cotton. With your fingers, squeeze and smash the strawberry mixture for 2 minutes. The steps used to remove and expose DNA from its cell are: breaking down the food type you are using by crushing it, for example a banana or strawberries, exposing the substance to a sodium chloride NaCl solution, subjecting the product to detergent solution dH2O , filtering the solution and lastly, the addition of ethanol.

The solution was mostly clear, but a little frothy and yellow from the soap. Many of the common multicellular many celled organisms you encounter have body cells that are diploid two copies of each chromosome and gametes egg and sperm that are haploid one copy of each chromosome. Which samples taken under clinical conditions were examined for genetic evidence that could link parent to child. Overall both methods successfully extracted DNA from solution. Squeeze the strawberry mixture with your fingers for 1 minute.

(DOC) Lab report for dna strawberry
Since the ethanol plays a key role in the extraction of strawberry DNA, I predict that the low the temperature of the ethanol is, the more DNA will be extracted. The end result was pretty fascinating. The chux and remnants were discarded after filtration. Discussion Although only the extraction of strawberry DNA was performed in this lab, this section will address the roles of each step taken and the reagents used during the extraction of DNA from animal tissue as well, and compare it to the steps taken in the strawberry protocol. Those charges stabilize the negative charge of the DNA, and thus allows the molecules to stay attached all together and to separate from their associated proteins 4, 8.

DNA Extraction from Strawberry Fruits using Youtube method Introduction: DNA extraction is a process which is used in the purification and removal of DNA from cells. Once the flow rate is minimal, the excess in the filter, consisting of cell debris and banana residue, can be disposed and then the filtrate is focused upon. After, the test tube is filled with the mixture you must add ice-cold alcohol until the test tube is halfway filled. It filtered very slowly because our mixture was so thick. Results Obtained The addition of 170 µL of 5M NaCl to the sample precipitated all the protein in the solution. While one would assume that their bodies would just readjust and revert back to having a genome that promoted effective water-based genes, that isn't the reality. Doctors also depend on DNA extraction for differential diagnosis and treatment of various diseases.

That is why these diseases are more prevalent in people who come from families where some members have suffered the same illness. DNA Extraction Lab: Strawberry DNA Extraction Lab: Strawberry Background: The long, thick fibers of DNA store the information for the functioning of the chemistry of life. Once the strawberry pulp was obtained, the heated salt water detergent was added. DO NOT POKE A HOLE IN THE FILTER PAPER! This could affect the purity of the precipitated DNA following the addition of ethanol. The membrane itself is composed primarily of phospholipids. Put the strawberries in plastic bag, push out all air, and use your hands to mash the strawberries for 2 minutes 4. In reality, the teenager proved he wasn 't the one who he was looking for, that caused this scenario.

The procedure has been widely used in forensics and laboratory studies. I found it fascinating how the isopropyl alcohol separated from the strawberry mixture and the DNA floated u p into it. We finally measured out 5 ml of isopropyl alcohol and added it to our test tube. To being the procedure you start by placing one strawberry in a zip lock baggie making sure all air is sealed out of the bag. The method of salting out is more effective than all the other methods of DNA extraction Seeker et al.

The sample is then uploaded to CODIS, a national network of DNA databases. DNA Exoneration Case Study 547 Words 3 Pages Statement of the Problem DNA has become a vital part of criminal investigations. Overall, this was an exciting experiment and I now have a more realistic idea of what plant DNA looks PV92: A Hoax Or Genetic Drift? Pull up the skewer. Even though the procedures vary considerably, they involve three main steps: lysis of cell wall, cell membrane and nuclear membrane, isolation of DNA from other cell inclusions, and purification of the extracted DNA. Also, it is important because, with the ability to extract DNA, scientists can identify or notice genetic disorders or other diseases by studying the Unit 3 Lab 3 Dna Extraction And Visualization 1241 Words 5 Pages Lab 3 — DNA extraction and visualization Journal -Madhu Thalari. Next, you must smash the strawberry and extraction buffer for a minute. The first step of the process was to obtain the weight of the plastic cup by itself, get a strawberry, remove the stem and leave, put it in the plastic cup and then record the weight of plastic cup with strawberry.

This buffer, which has detergent in it, is to dissolve the cell and nuclear membranes and salts to break the ionic bonds between the histones and DNA, it separates DNA from strawberry. The way this occurs is when NaCl is added to the solution the molecule dissolves and forms ions. It also releases the chemicals cellulase and pectinase, which help break down the cell wall. Dip the bamboo skewer into the test tube where the alcohol and strawberry layers meet. Behavior, personality, body size, fingerprints, and skin color are all determined by the blueprint encoded in the DNA. The supernatant was then carefully poured off into a liquid discard beaker and the tube placed upside down on a paper towel to drain and left for 5 minutes to allow ethanol to fully evaporate. This implies that growth was affected more than seed pod production in the presence of competition.
