A group of molecules called DNA is in charge of carrying and transmitting genetic material from par ents to offspring. The DNA structure is similar to a twisted ladder. The image above shows what is referred to as this structure's double-helix shape. It is a nucleic acid, and nucleotides are the building blocks of all nucleic acids. Mar 18,  · View from SCIENCE at Martha Ellen Stilwell School of the Arts. Answer Key Name: _ Date: _ Period: _ Worksheet - Structure of DNA and. • DNA is wrapped around an octamer of histone proteins • Nucleosomes are linked by an interconnecting H1 histone Nucleosomes serve two key functions: • They help to supercoil DNA (improves packaging) • They help to regulate transcription. DNA gets the first part of its name from our first ingredient, the sugar molecule, which is called deoxyribose, but all the really significant stuff, the genetic coding that makes you you, is found among the four nitrogenous bases: adenine, thymine, cytosine, and guanine. Deoxyribonucleic acid or DNA is the molecule of heredity. It contains thc genetic blueprint far life. For organisms to grow and repair damaged cells, cach cell must bc capable of accurately copying itsclf. So how does the structure of DNA allow it to copy itself so accurately? Model 1 - The Structure of DNA Helix Model of DNA N de Phosphate. Outline how Franklin and Wilkins used X-ray crystallography to elucidate the structure of DNA Describe, with the aid of the diagram, the organisation of DNA into chromatin within eukaryotic cells Differentiate between euchromatin and heterochromatin. DNA replication is semi-conservative because when a new double-stranded DNA molecule is formed: • One strand is from the original template molecule (i.e. conserved) • One strand is newly synthesised (i.e. not conserved) Meselson and Stahl treated DNA with a heavier nitrogen isotope (15N) and then replicated in the presence. DNA REPLICATION AND PROTEIN SYNTHESIS ANSWERS 1. DNA is made of nucleotides. Each nucleotide consists of a nitrogen base, a phosphate group, and a deoxyribose sugar. 2. DNA will replicate itself when the cell is undergoing cell division, that is, new cells are being made from pre-existing cells. Examples of when this will occur are sperm and ova.
