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.
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
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).
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.
DNA is composed of six different subunits (or smaller molecules): Guanine (a base) Phosphate group Thymine (a base) Deoxyribose (a sugar) Adenine (a base) Cytosine (a base)
