Bio 1 Lab: Electrophoresis and DNA fingerprinting Jani Lynette Hagen October 31‚2014 U74644799 Electrophoresis is a technique which uses an electric field to separate molecules‚ allowing for identification and characterization of the molecules. It is commonly used to separate nucleic acids and protein molecules of various sizes. To prepare the gel for electrophoresis the amount of agrose needed must be calculated. For a 0.8 percent gel 0.8 grams of agrose is necessary per 100 ml of buffer. The DNA

extract DNA from a strawberry using limited household items. This was accomplished with the prior knowledge that the DNA is stored in the nucleus of the cell‚ and that is an extraction buffer would be needed to acquire the DNA. This experiment had no control group‚ however‚ if there was a control group it might be a group with no extraction buffer. The independent variable in this experiment is the extraction buffer. The dependent variable in this experiment is the ability to extract DNA. The constants

Mrs. Strait Period 7 1-9-12 Drosophila Melanogaster: Predicting Traits Lab Report The purpose of this study is to get an accurate look on how genetics work‚ and to practice determining the different traits within the species. D. melonogaster are useful because they are easily cultured and they reproduce very quickly. The eye color data supports past genetics problems because it can be predicted‚ and used in Punnett squares to aid in the prediction. If the P generation consists

Mitochondrial Replacement Therapy There are many differing opinions concerning mitochondrial replacement therapy in the United States. Such as the child might have a negative perception of themselves‚ The child may feel disconnected from their mother‚ and they may have issues with their ancestry. Another opinion is the procedure needs to be further tested to ensure MRT’s validity. There are a couple of diseases associated with the mutation in the mitochondria; LHON disease and Leigh’s disease

Mitochondrial Diseases are very diverse. Specialized organelles in every cell of the body (only red blood cells lack mitochondria). Mitochondria generate more than 90% of the energy required by the body. Mitochondrial dysfunction depletes cells of energy causing cell damage and even cell death. Due to the high energy requirements of brain and muscle‚ mitochondrial disease typically affect these parts of the body causing Brain and Muscle disease. Other organs are frequently affected including: eye

The OODA Loop & HEMA This is not a reworking or rewording of any historical master’s writings‚ nor some kind of new Rosetta Stone‚ there is nothing new under the sun and to think otherwise is a fallacy [1]. This short paper simply describes the decision making process that all combatants make; the feedback cycle between decision-maker and the environment‚ how we can use this model as a tool to aid and improve our actions in the fight and in scholarly interpretations. The OODA Loop touches upon

Feedback loops are critical in maintain homeostasis for organisms. The two kinds of loops are positive and negative. Negative is especially influential in process of homeostasis because of the ability to regulate amounts thus making negative feedback often times an asset. The feedback loops and hormones are both critical for each other to function. The actions of feedback loops and hormones can then change the concentration gradient. The kidney is a vital organ to maintain a proper level of

The Future Loop Jack is a flexible man that has the ability to move all the bones in his body without even practicing yoga. He could survive many years without food. He came from a family of four‚ a sister‚ brother and his parents. They were not very wealthy but had enough for the family to survive. Jack didn’t achieve anything in his childhood other than gold medals in flexibility competitions. One day while Jack was on the way to the market‚ he noticed a big man with a young face. The big man

Alex Polnaszek Fertilizer Composition and Use Fertilizers have helped farmers and the production of food in this country immensely. They have allowed farmers to have a higher yield of food per acre despite some deteriorating soil conditions. There are three main elements in each bag of fertilizer. They are nitrogen‚ phosphorus and potassium and are represented on the outside of the bag in that order. Each of the three elements has a different benefit to the growth of a plant. Plants use
