2 mar 2012 · This document discusses the structure, properties, and functions of DNA. It describes DNA as a polymer composed of deoxyribonucleotides that carries the genetic information found in chromosomes, mitochondria, and chloroplasts.
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of two different classes of nitrogen-containing bases: the purines and pyrimidines. The most commonly occurring purines in DNA are adenine and guanine: Figure 1.2.1: Purines. The most commonly occurring pyrimidines in DNA are cytosine and thymine: Figure 1.2.2: Pyramidines
11 maj 2017 · It describes that nucleic acids consist of sugars, nitrogenous bases, and phosphate groups. The four main nitrogenous bases are adenine, guanine, cytosine, and thymine in DNA or uracil in RNA. The document then discusses the primary, secondary, tertiary, and quaternary structure of nucleic acids.
9 lut 2014 · It describes the key components of DNA including the sugar-phosphate backbone, nitrogenous bases, and how the bases pair up in the double helix structure. It also discusses different DNA structures like A, B and Z-DNA and how DNA packages into nucleosomes and chromosomes.
DNA Structure. Outline how Franklin and Wilkins used X-ray crystallography to elucidate the structure of DNA. ...............................................................................................................................................................................
DNA is a polymer of nucleotide monomers, each consisting of a phosphate, a deoxyribose sugar, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). The nucleotides of DNA are arranged into a double helix based on the rules of base complementarity.
27 mar 2021 · A complete introductory KS4 lesson on the structure of DNA, including a starter, lesson objectives, a range of tasks for students to complete and a focus on protein synthesis and understanding DNA mutations, as well as RAG strategies for building students' confidence with learning new keywords.
