Topps may have lost its NFL contract in â64, but getting Namath kept those old AFL sets relevantâand fairly valuable. Joe Willieâs rookie card is hard to find centered and because of the myriad of condition sensibilities, itâs one of the most expensive football cards ever to come out of the Topps roster.
Report Abuse. Chromosomes are made up of DNA packaged with histones and other proteins. DNA is deoxyribonucleic acid, an extremely long polymer whose repeating units are each made up of a phosphate plus a deoxyribose sugar plus a nitrogenous base.
The monomers from which nucleic acids are constructed are called nucleotides. Each nucleotide consists of three components: a nitrogenous heterocyclic base, either a purine or a pyrimidine; a pentose sugar; and a phosphate group.Different nucleic acid types differ in the structure of the sugar in their nucleotides; DNA contains 2-deoxyriboses while RNA contains ribose.how more I know that nucleic acids are made up of nucleotides, and nucleotides are made up of a nitrogenous base, a sugar (either ribose for RNA or deoxyribose for DNA), and a phosphate group.
