The Structure and Function of DNA - Molecular Biology of the Cell ... A DNA Molecule Consists of Two Complementary Chains of Nucleotides A DNAmoleculeconsists of two long polynucleotide chains composed of four types of nucleotidesubunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bondsbetween the baseportions of the nucleotides hold the two chains together (Figure 4-3). DNA - structure The final piece that we need to add to this structure before we can build a DNA strand is one of four complicated organic bases. In DNA, these bases are cytosine (C), thymine (T), adenine (A) and guanine (G). Note: These are called "bases" because that is exactly what they are in chemical terms.

DNA Structure | Biology Dictionary The base pairs of DNA are: Adenine-thymine Guanine-cytosine Base pairs in DNA The two strands of the double helix run in opposite directions to one another, meaning that the 5' end of one strand faces the 3' end of the other. This is called the antiparallel orientation, and it is essential for successful DNA replication.

The Structure Of DNA and RNA : Plantlet A DNA molecule consists of two polynucleotide chains, linked by hydrogen bonds between bases. In DNA there are four bases - adenine always pairs with thymine, and cytosine always pairs with guanine. RNA, which comes in several diff erent forms, has only one polynucleotide chain, although this may be twisted back on itself, as in tRNA.

You don't need to be an artist, its... DNA: Structure, Forms and Functions (With Diagram) DNA contains β D 2′-deoxyribose sugar. It is a five-carbon sugar; hence it is a pentose sugar. Since one oxygen atom at the 2′ carbon is missing it get its name 2′-deoxy. The 2′- deoxy-containing backbone is more resistant to hydrolysis than the riboform. D-ribose does not mean dextrorotary ribose.

DNA Structure and Shape | Ask A Biologist Image by Madprime via Wikimedia Commons. A closer look at the chemical structure of DNA shows four main building blocks. We call these nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). DNA also includes sugars and phosphate groups (made of phosphorus and oxygen). These make the phosphate-deoxyribose backbone.
