Sep 11, 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).
May 5, 2010 · 1. DNA is made up of deoxyribose, phosphate groups, and four nitrogenous bases (adenine, guanine, cytosine, thymine). 2. The bases pair up through hydrogen bonding between complementary base pairs (adenine with thymine, cytosine with guanine). 3.
Aug 1, 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
A Brief History of DNA (deoxyribonucleic acid): Discovery of DNA by many different scientists 1928 – Griffith – studied how bacteria made people sick; found that a gene could change harmless bacteria into disease-causing ones 1944 – scientists led by Avery – DNA is a nucleic acid that stores and transmits the genetic information from ...
DNA Structure. A gene is a section of DNA that codes for a protein. Each unique gene has a unique sequence of bases. This unique sequence of bases will code for the production of a unique...
