This Technical Bulletin was prepared by members of the SSFI Plank-Platform Section. SSFI is a trade association comprising manufacturers of shoring, scaffolding, forming, suspended scaffolding, and planks-platforms. The institute. focuses on engineering and safety aspects of scope products.
The basic building block of DNA is the nucleotide. The nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.Cytosine and thymine are pyrimidine bases, while adenine and guanine are purine bases.The sugar and the base together are called a nucleoside.he nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.
Nucleotides are the basic structural units of nucleic acids, which control the production of proteins in living organisms. The nucleotides are made up of a phosphate group, a pentose sugar, and a nitrogen base.This shows the basic structure of a nucleotide.This example has the sugar ribose, and is characteristic of RNA.he nucleotide could contain the sugar deoxyribose, characteristic of DNA. For DNA, the bases may be adenine, guanine, cytosine or thymine. For RNA the bases are adenine, guanine, cytosine and uracil.
