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.
28 lis 2015 · The document summarizes the structure of DNA. It describes that DNA is composed of four nucleotides - adenine, guanine, cytosine, and thymine. These nucleotides are linked by phosphodiester bonds to form a double helix structure.
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 is a large molecule made of small parts called nucleotides. Each nucleotide contains three parts: 1. sugar (deoxyribose) 2. phosphate group 3. nitrogen base (any of 4, adenine, thymine,...
The document summarizes key concepts about DNA structure and function including: 1. DNA replicates in a semi-conservative manner where each new DNA molecule contains one old and one new strand. 2. DNA replication requires a DNA template, nucleotides, DNA polymerase, and energy.
The structure of DNA A. Important features of the DNA structure: 1. Right-handed double helix 2. The helices are antiparallel 3. Each helix has a series of nucleotides held together with phosphodiester bonds between the OH groups in two adjacent sugar residues. 4.
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).
