Pine green is a rich shade of spring green that resembles the color of pine trees. It is an official Crayola color (since 1903) that is this exact shade in the Crayola crayon, but in the markers, it is known as crocodile green. The first recorded use of pine tree as a color name in English was in 1923.
DNA Structure. Â­DNA is oÂ­ne of the nucleic acids, information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nucleic acid). DNA is found in the nucleus of every human cell.(See the sidebar at the bottom of the page for more about RNA and different types of cells).The information in DNA:he base pairs in DNA are adenine with thymine and cytosine with guanine. DNA has a spiral staircase-like structure. The steps are formed by the nitrogen bases of the nucleotides where adenine pairs with thymine and cytosine with guanine.
DNA is found in the chromosomes of the nucleus in a cell and it carries hereditary information. RNA is located in the cell but not in the nucleus. Just as proteins consist of long chains of amino acids, DNA and RNA consists of nucleic acid chains called nucleotides. Nucleotides are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil. They are abbreviated (A, C, G, T, U).
