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.
24 wrz 2018 · Goal. To understand the structure and chemistry of DNA and the significance of the double helix. Objectives. After this chapter, you should be able to. explain the structural basis for the directionality of polynucleotide chains. describe how hydrogen bonding and geometry dictate base pairing.
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.
24 wrz 2018 · Goal. To understand the chemistry of DNA synthesis and how DNA is replicated with high accuracy. Objectives. After this chapter, you should be able to. describe the experiment that proved that DNA replication is semi-conservative. diagram the reaction for phosphodiester bond formation. explain the energetics of DNA synthesis.
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.
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).
