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 molecules are carriers of an organism's genetic information. A cell's chromosomes are made from DNA molecules and associated proteins. This chapter looks at the discovery and structure of DNA-the molecule of life.ucleotides are made of one nitrogenous base, one phosphate molecule and one sugar molecule (deoxyribose in DNA and ribose in RNA) There are four different types of nucleotides found in DNA. When drawing the DNA molecule model these nucleotides are referred to by their 'initials': 1  A is for adenine.
