DNA! spooled gene chromosomes chromatin double helix
1953 Wilkins Franklin Watson Crick
Nucleotides are the monomer of nucleic acidsThis component varies
nucleotides creates a nucleic acid, a polymerThe chain of nucleotides creates a nucleic acid, a polymer
sugar phosphate base pairs covalent bond H-bond N-base
DNA has 4 nucleotides purines pyrimidines
The base pair rule makes thetwo helices complementary Adenine bonds to Thymine Cytosine bonds to Guanine
DNA is replicated when cells reproduce (mitosis, meiosis) • each old strand acts as a template for a new one • the two stands each contain half of the original Thus replication is semi-conservative
RNA is a nucleic acid with a slightly different structureSingle helix Ribose sugar vs deoxyribose of DNA * uracil pairs with adenine during RNA synthesis
Function of each differs, but are complementaryRNA rewrites and interprets the code multiple types of RNA DNA segments of the sequence - genes - code for proteins
Characteristic of Life!! DNA is found in all living things and has the same structure!
DNA Replication Section 12-2 in Textbook. ANIMAL CELL.
DNA Introduction. What is DNA? Genetic information of life Type of Nucleic Acid Double Stranded.
Protein Synthesis Study Guide. DNA and RNA DNA has 2 strands, RNA has 1. DNA has thymine, RNA has uracil DNA has deoxyribose, RNA has ribose.
From DNA to Protein. Knowledge of Nucleic Acid Chemistry Is Essential to the Understanding of DNA Structure.
Nucleic Acids Nucleic acids provide the directions for building proteins. Two main types… DNA – deoxyribonucleic acid Genetic material (genes) that.
Nucleic acids Nucleic Acids Information storage.
Nucleic Acids Nucleic Acid Basics Contain instructions to build proteins 2 types: – DNA – RNA Composed of smaller units called nucleotides – Monomer:
8.1 DNA Structure & Function. Nucleic Acids DNA & RNA are nucleic acids Monomer? ▫Nucleotides 5-C Sugar P N- Base.
Nucleic Acids. Nucleic acids are large biomolecules (polymers) – essential for all known forms of life Include DNA and RNA Made from long strands of nucleotides.
DNA: the blueprint of life. Where do you get your DNA? DNA is passed from parent to offspring. Where do we find DNA? DNA is in the nucleus of every cell.

Chap. 10 : Nucleic Acids & Protein Synthesis I. DNA – deoxyribonucleic acid - function – store and use information to direct activities of the cell and.
DNA. Nucleic Acids Informational polymers Made of C,H,O,N and P No general formula Examples: DNA and RNA.
Unit 2 – PART A Inside the Nucleus DNA Sturcture.
Gene Expression Gene: contains the recipe for a protein 1. is a specific region of DNA on a chromosome 2. codes for a specific mRNA.
D.N.A. DeoxyriboNucleic Acid A molecule that contains our genetic information Is found in the nucleus of almost all cells wound up into chromosomes.
Nucleic Acids DNA, RNA, ATP. DNA – Deoxyribose Nucleic Acid Function: Codes for genetic material/instructions Production: Located on chromosomes in the.

DNA and RNA. Rosalind Franklin Worked with x-ray crystallography Discovered: That DNA had a helical structure with two strands.
Deoxyribonucleic Acid Structure Function Replication Recombinant DNA DNA versus RNA.
Family Resemblances Why do siblings often look alike?
Y Stock NUCLEIC ACIDS DNA DNADNA is a nucleic acid. Within the nucleus chromosomes are made of DNA. DNA contains instructions controlling protein synthesis.
Chapter 12 DNA: The Molecule of Heredity. Objectives Analyze the structure of DNA Determine how the structure of DNA enables it to reproduce itself accurately.
1. What does DNA stand for? 2. What shape does the DNA molecule have? 3. What does DNA do for your cells? 4. Why is DNA important to you? Stamp Sheet:
WARM UP Which scientists performed experiments with viruses?
Nucleic Acids The amino acid sequence of a polypeptide is programmed by genes. Genes consist of DNA, which is a polymer belonging to the class of compounds.
DNA, RNA & Protein Synthesis. A. DNA and the Genetic Code 1. DNA controls the production of proteins by the order of the nucleotides.
DNA (deoxyribonucleic acid) is a two stranded molecule called double helix Each strand are made of smaller parts called nucleotides The two strands.
Nucleic Acids The Genetic Material. Two types of Nucleic acids RNA RNA DNA DNA.
DNA RNA Made up of C, H, O, N, P Nucleotides are the monomers of Nucleic Acids Phosphate Group 2.5-Carbon Sugar (Dexoyribose or Ribose)
