Your unique code of DNA defines your stature, your health condition(s), your face, etc. For example, sickle cell anemia is caused by a small flaw in your DNA and a single changed amino acid in hemoglobin and creates a lifelong condition. As mentioned previously, DNA also codes for muscle structure, especially facial muscles and the shape of your facial bones. Your zygomatic arch, orbicularis oris, orbicularis oculi, mandible, all vary in shape from person to person, and combining these variables creates the resemblance of a face. How can tools of molecular biology be used to compare the DNA of two individuals?

This replication is carried out by enzyme called helicase which break the hydrogen bonds holding the complementary bases of DNA together {A with T, C with G}. 3. Separations of two single strands of DNA create Y shape called replication fork. Two separated strands will act as templates for making the new strand of DNA. 4.

Introduction The purpose of this lab is to investigate the enzyme action of proteases in pineapple. Enzymes are biological catalyst which speeds up the chemical reaction without being used. Enzymes are protein that is folded into complex shape that allow smaller molecules to fit into them, and also speed up the chemical reaction. It does not get used in chemical reaction, so it can get reuse again. Proteases are enzymes that breaks down protein, specifically digestive proteins, and it is any enzymes that can perform proteolysis.

The foreign DNA is inserted at random locations into the DNA of the fertilized egg. The egg is then implanted into the oviduct of a surrogate animal, where the egg then develops. This method has been used to create many kinds of transgenic animals, from mice to large animals such as cattle. Some examples of current genetically modified organisms: Food: Golden rice is modified so that it produces vitamin A. although it’s still waiting regulatory approval, its purpose is to in rich 3rd world countries in a more balanced meal and healthier diet Animals: Goats have been adapted to produce human antithrombin, Antithrombin is a way in which a blood clotting disease in humans is treated. Goats have also been genetically altered to yield spider silk, which could be used for artificial bulletproof

Amylase is the enzyme secreted by the oral cavity and can be found in the saliva glands. As soon as mechanical digestion begins, amylase digest the long, starch polysaccharide molecules found in food and breaks them down into smaller, simpler disaccharide molecules known as maltose. Maltose still needs to be digested further for absorption to take place in the small intestine. So, the enzyme maltase breaks maltose down into glucose. Other disaccharides are broken down by other carbohydrase enzymes.

These proteins are made up of monomers known as amino acids. Each amino acid is made up of an amino group, a carboxyl group and a side chain (Reece, J. B., Urry, L. (2016). Campbell biology. Boston Pearson).

In this experiment, we want to clone SOD gene into pUC19 plasmid of E.coli. Before ligating the target gene into the plasmid, the host cell needs to be competent to accept the vector. E.coli is not a naturally transformable bacterium thus; it needs to become transformable by chemical transformation. This technique is very useful to make competent cells that later will be used for transformation experiment in a short time. Actually there are not so much difference between chemically competent cells and competent cells prepared by electroporation.

Discussion: 1. Explain why each of the following were used in the extraction process. • Detergent Detergent was used as detergent has the ability to break down the plasma membrane of the peas cells. This then allows the meat tenderiser to enter the cells and allows the DNA to exit the cells. • Meat tenderiser The meat tenderiser contains an enzyme that is able to break down proteins, so its job is to break down the nucleus to release the DNA and also to break the enzymes in the cells that break down the DNA

I. Title: Mass and Mole Relationships in a Chemical Reaction II. Background: Percent yield is the ratio of actual yield to theoretical yield. Amount in percent of one product formed in chemical reaction. Actual yield is the information found is experiments or is given.
