HEMOGLOBIN & MYOGLOBIN Protein Function HEMOGLOBIN: WHEN THE FIRST SUBUNIT OXYGENATES OR DEOXYGENATES THE FOLLOWING THREE SUBUNITS FOLLOW SUIT AND THE SHAPE OF THE HBG MOLECULE IS CHANGED. Oxygenated • R state (relaxed) • When O2 is present‚ it binds to the iron attached to each heme and tugs on it which in turn flattens the heme to a planar shape • The color of oxygenated blood is red (macroscopic) • Carried from the heart throughout the body by the systemic arteries Deoxygenated

Should Recycling Be Mandatory? Did you know?... Cashmere just released their new product. Cashmere Envirocare‚ is made of 100% recycled fibre and is also 100% soft! This surely shows that Cashmere cares for the environment...Do you? All of us can save Earth from running out of paper and other resources‚ But most people don’t know how to accomplish this. In my opinion‚ recycling is the best way to make the Earth a better place. Unfortunately‚ this method is not so popular these days. There are

The hypothesis for this lab is if strawberry DNA is separated from other components‚ then when it is placed in a insoluble solution the DNA can eventually be isolated. DNA is deoxyribonucleic acid. Its a self replacing material present in all living organisms as the main constituent of chromosomes. It is the fundamental and distinctive characteristics of someone or something‚ especially when regarded as unchangeable. DNA extraction is the removal of deoxyribonucleic acid from the cells or viruses

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information‚ composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The

Recombinant DNA Technology Benefits in Many Areas Recombinant DNA Technology is a DNA-based tool that allows scientists to find individual genes‚ cut them out‚ and insert them into the genome of another organism. Recombinant DNA Technology has been used to create different types of medicines for example human insulin. People with diabetes do not produce enough insulin for their own bodies‚ and in a lot of cases‚ they are allergic to non-human insulin. Due to the creation of Recombinant DNA Technology

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

The Importance of DNA Evidence What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually‚ DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell‚ a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue‚ sweat‚ bone‚ the root and shaft of hair‚ earwax‚ mucus

DNA Extraction of a Musa acuminata Biology Lab Report \Analyze and Interpret A number of steps are required to isolate DNA from cellular contents. Describe what happens at each step‚ and why it acts to separate the parts of the cell. /6 There are three specific steps required to isolate DNA from its cellular contents. 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

determining paternity to name a few. DNA based techniques are a sub-discipline of forensic biology and are a crucial component in this field of work. DNA analysis began in the mid 1980’s and revolutionised the field of forensic science. With continual refinement of DNA analysis methods in crime laboratories over the years‚ small amounts of blood‚ saliva‚ skin cells and other biological material can now be used to develop leads and confirm or disprove an account of the crime.
