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
Nucleic Acids The Genetic Material. Two types of Nucleic acids RNA RNA DNA DNA.
The Second of the Big Four Nucleic Acids. These are macromolecules are made up of nucleotides – Polymer - nucleic acid – Monomer - nucleotide Contain.
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.
Nucleic Acids Nucleic Acid Basics Contain instructions to build proteins 2 types: – DNA – RNA Composed of smaller units called nucleotides – Monomer:
Nucleic acids Nucleic Acids Information storage.
Let’s Review! What is a macromolecule?
AP Biology Nucleic acids AP Biology Nucleic Acids.
Family Resemblances Why do siblings often look alike?
WARM UP Which scientists performed experiments with viruses?
Chapter 10 – DNA, RNA, and Protein Synthesis
DNA & Genetics Biology. Remember chromosomes? What are genes? Made up of DNA and are units of heredity; unique to everyone What are traits? Are physical.
Unit 2 – PART A Inside the Nucleus DNA Sturcture.
DNA: The Molecule of Heredity
DNA: Structure and Function. DNA Structure Deoxyribonucleic acid. A macromolecule composed of two strands of monomers called nucleotides. These strands.
KEY CONCEPT DNA structure is the same in all organisms.
8.1 DNA Structure & Function. Nucleic Acids DNA & RNA are nucleic acids Monomer? ▫Nucleotides 5-C Sugar P N- Base.
