INTRODUCTION. In this activity, you will build your own model to understand how DNA works. DNA is a simple molecule made up of four types of chemical building blocks called nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
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.
KEY CONCEPTS. 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.
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.
11 wrz 2019 · DNA is a double-stranded molecule that forms a helical structure. It is composed of nucleotides, each containing a phosphate group, deoxyribose sugar, and a nitrogenous base. There are two types of bases: purines (adenine and guanine) and pyrimidines (cytosine and thymine).
20. List the 3 basic steps of DNA replication: a. b. c. One of the strands comes from the original strand. When creating new cells, each cell needs DNA. DNA are the instructions for the cell - without DNA the cell would not function. DNA double helix, Chromosome, Nucleus Helicase opens up the helix.
