Bio molecules. Biological Molecules “Molecules of Life”. Also called Organic molecules. Biological molecules are large molecules found in all living things. Biological Molecules. 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids. 4 Types of Biomolecules. CHNOPS.By christine-thulani
Chapter 12 Molecular Genetics. 12.1 DNA: The Genetic Material. Discovery of the Genetic Material. Chromosomes are about 50% nucleic acid and 50% protein, which is the genetic material? Most scientists thought that protein was the genetic material because protein is more complexBy quinn-nielsen
NOTES: 12.2 – 12.3 DNA Structure & Replication. 12.2: DNA Structure. ● it was known that DNA was made up of nucleotides joined into long strands by covalent bonds…but HOW were they connected…what was the structure?. DNA Structure. ● Made up of nucleotides (monomer)By verat
1 The Genetic Code of Genes and Genomes. DNA: Molecule of Heredity. Inherited traits are affected by genes that are transmitted from parents to offspring in reproduction Genes are composed of the chemical deoxyribonucleic acid = DNA. Fig. 1.6. DNA: Molecule of Heredity.By epinkney

DNA-The Double Helix. Answer Key. 1. Write out the full name for DNA. D eoxyribo N ucleic A cid. 2. What is a gene?. A gene is a segment of DNA that codes for a particular protein which in turn codes for a trait. 3. Where in the cell are chromosomes located?.
DNA: The Double Helix. Deoxyribonucleic Acid. DNA Structure. DNA Structure. DNA has a basic structure called a “double helix” DNA has two strands that form the spiral shape These strands are made of repeating subunits called nucleotides. Nucleotides. Nucleotides. Composed of three parts:
DNA – The Double Helix. Recall the nucleus is often called the “ control center ” because it controls all of the cell’s activities. (eg. Cellular reproduction). Chromosomes. Are threadlike structures in the nucleus, made of DNA. DNA. Deoxyribose nucleic acid
DNA Printing the double helix. Using 3D Printers. Produced By- Dave White. Head of D&T Clevedon School. DNA. Most people have heard of DNA and know that it has something to do with genetics, few know that DNA stands for Deoxyribonucleic acid .
DNA molecule described as double helix. WE EXPRESS OUR DNA as we need it………. The ENTIRE DNA MOLECULE can Replicate: Then You have 2 from 1 (DNA REPLICATION---Leads to MITOSIS ..one cell goes to two cells. OR
Answer: Francis Crick and James D. Watson. Can you name these scientists? ( double helix structure of DNA ).
