6 wrz 2014 · Download now. 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.
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.
1 sie 2014 · Structure of DNA – Levels of Complexity • Nucleotides = building blocks • Strand = covalently linked nucleotides in a linear fashion • Double helix = two strands twisted together • Chromosome = association of DNA with proteins to organize strands into a compact structure • Genome = complete complement of an organism’s genetic material
19 paź 2010 · DNA is composed of 2 chains of nucleotides that form a double helix shape. The two strands are antiparallel. The backbone of the DNA molecule is composed of alternating phosphate groups and sugars. The complimentary nitrogenous bases form hydrogen bonds between the strands.
The experiment: Take DNA from a variety of species and hydrolyze it to yield individual pyrimidines and purines. Determine the relative concentrations of the A, T, C and G bases.
DNA Structure. 1. LESSON: What is the structure of DNA? I use a powerpoint lesson to introduce the topic with my students. You can find it on my website or on TpT. 2. MODELS: It’s fun to have students build some sort of model. Here is a template that I use to have students build models out of paper.
