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

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

FORENSIC DNA ANALYSIS Forensic serve both the living and the dead -- those who are victims‚ suspects‚ survivors‚ and those who are left behind. Forensic nursing blends nursing science with medicine‚ law‚ and criminology. At its core‚ this specialty seeks to address healthcare issues that have a medico legal component. Long before holding the designation of forensic nurse‚ nurses provided care to the victims and perpetrators of violence. History reveals that in the 14th century‚ performed gynecologic

A detective is a police officer‚ whose duty is to detect criminals‚ by in-depth investigation of cases. When attempting to solve a crime‚ detectives conduct a criminal investigation that seeks all the facts about a crime to help determine the truth: what happened and who is responsible. This involves making a preliminary and final investigation. A detective’s task is to gather‚ organize‚ and use information about social behavior. To effectively complete that task a detective should possess

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

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

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry
