The Molecule of Life: DNA The Molecule of Life: DNA The purpose of this laboratory exercise is to extract and visualize DNA from fruit. The objectives of the laboratory exercise are: To understand where DNA is found To isolate DNA To understand how DNA is extracted

The Structure of DNA. The earth is 150 billion m or 93 million miles from the sun. DNA by the Numbers. Each cell has about 2 m of DNA. The average human has 75 trillion cells. The average human has enough DNA to go from the earth to the sun more than 400 times.

Lecture 1. Molecular Structure of DNA and RNA part 1 Chapter 9, pages 227 - 236. What is genetics?. It is the branch of biology concerned with the study of heredity and variations. Mendel.

Polymerase chain reaction. Who would have thought a bacterium hanging out in a hot spring in Yellowstone National Park would spark a revolutionary new laboratory technique? The polymerase chain reaction, now widely used in research laboratories and doctor's offices, relies on the

FCH 532 Lecture 10. Extra credit posted on website, due on Friday (email or typed copy) Chapter 29. Sugar Pucker. Ribose rings will undergo sugar pucker (become slightly nonplanar).

Molecular Basis of Inheritance. Chapter 16. Objectives. Understand how the structure of DNA was determined Understand the role of DNA in the cell and in inheritance. Categorizing the Role. The function of DNA was first described from tests utilizing microbes and viruses

Genes and How They Work. Chapter 15. The Nature of Genes. Early ideas to explain how genes work came from studying human diseases. Archibald Garrod studied alkaptonuria, 1902 Garrod recognized that the disease is inherited via a recessive allele

Review. What monomers make up protein polymers? What type of chemical bond is formed between these monomers? What are the four levels of structure in proteins?. Review. What monomers make up protein polymers? Amino acids

DNA Replication. 3’. Parental DNA Molecule. 5’. Replication Fork. 3’. 5’. DNA Replication. Origins of replication 1. Replication Forks : hundreds of Y-shaped regions of replicating DNA molecules where new strands are growing. Bubbles. Bubbles. DNA Replication.

Genes and Gene Expression Informational macromolecules = DNA, RNA, Protein Unit of information = gene (a segment of DNA specifying a protein, rRNA or tRNA) Genes = coded by DNA or RNA (HIV). CHAPTER 7 Essentials of Molecular Biology.

Chapter 8. From DNA to Proteins. Introduction to Protein Synthesis. 8.1 Identifying DNA as the Genetic Material. Griffith finds a ‘transforming principle.’. Griffith experimented with the bacteria that cause pneumonia. He used two forms: the S form (deadly) and the R form (not deadly).

Watson and Crick(1953)- Double helix model of DNA. Double helix model of DNA. Early models of DNA.

Genome Conservation Society. A society for the past and the future of mankind. What is the Genome ? Word of the President. Purpose of the society GenomeShrine practical . Genome Conservation Society. WORD OF THE PRESIDENT. NOT THE BLOOD BUT THE DNA IS IMPORTANT

DNA Introduction. Background. Body consists of 60 trillion cells Most of these cells contain a nucleus Not mature red blood cells Each nucleus contains the genetic material in chromosomes Genes are found on chromosomes. nucleus. Chromosome → Gene → DNA. Background.

From Gene to Protein. The connection between genes and proteins The synthesis and processing of RNA The synthesis of protein. The Connection between Genes and Proteins. The study of metabolic defects provided evidence that genes specify proteins One-gene-one-enzyme hypothesis.

Genetics Quiz. Click the picture to begin the quiz. Question 1. The man considered the father of modern genetics, who also determined how genes are inherited is : Charles Darwin Louis Pasteur Isaac Newton Gregor Mendel. Question 1 Correct!.

WARM UP #4 2/5/13. Where did the virus originate? A vector is an intermediate carrier for the virus. What species was the vector in CONTAGION? What species was the 1 st host for the virus? What are the symptoms?. Components and Structure of DNA—Chromosomes and DNA Replication.

Nucleic acids:. Information molecules. Nucleic Acids . Examples DNA DeoxyriboNucleic Acid RNA RiboNucleic Acid. RNA. proteins. DNA. Nucleic Acids. Function: genetic material stores information genes blueprint for building proteins DNA  RNA  proteins transfers information

DNA Replication. DNA Length. DNA molecules are surprisingly long. The nucleus of a human cell contains more than 1 meter of DNA. DNA must be folded and coiled in order to fit in such a small space. Structure of Chromosomes. Chromosomes are made up of chromatin .
