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

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

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

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

procedure for extracting DNA‚ collecting DNA samples‚ and to observe the physical characteristics of DNA Background: The wild strawberry is a diploid because it only has two sets of chromosomes. While the grocery store kind is an octoploidy because it has eight sets of chromosomes. The reason we chose the grocery store strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break down the cell walls making it easier to extract the DNA. We will be using a solution

DNA Extraction from Wheat Germ and Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled

1. Outline the Steps of DNA: a. DNA Replication begins at the Origin of Replication b. Helicase cuts hydrogen bonds and separates DNA in half c. Semiconservative replication produces two copies that each contained one of the original strands and one entirely new strand. d. Topoisomerases catalyze and guide the unknotting of DNA e. Single Strand Binding Proteins attach to the halves and keep the DNA molecules separated (they are needed because the sides are attracted to each other and with out
