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.
6 wrz 2014 · • DNA consists of two chains of nucleotides in a ladder-like structure which is twisted (Double Helix) • Used data of M.H.F. Wilkins and Rosalind Franklin, early 50’s • Wilkins and Franklin studied the structure of DNA crystals using X-rays. • The X pattern suggested the structure of DNA was a helix.
11 maj 2017 · DNA has two polynucleotide strands that wind together to form a long, slender helical molecule. The strands run in opposite directions and are intertwined in a clockwise direction. The structure is stabilized by hydrogen bonds between the nitrogenous base pairs and the negative charge of the phosphate groups.

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
Presentation transcript: 1 DNA Structure. 2 DNA Structure DNA consists of two molecules that are arranged into a ladder-like structure called a Double Helix. A molecule of DNA is made up of millions of tiny subunits called Nucleotides. Each nucleotide consists of: Phosphate group Pentose sugar Nitrogenous base.
