Foot board measure is basically a calculation of how many boards of a particular size that it takes to build a 12-by-12-inch square block, which means that length takes on a more significant role in the calculation of bundle than width and thickness.
The shape of adenine is complementary to either thymine in DNA or uracil in RNA. Cytosine (C). Cytosine (C) is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). The nucleoside of cytosine is cytidine.
Nucleotides. Both DNA and RNA are nucleic acids, and are polymers of nucleotides. A nucleotide has three components: a pentose (five-carbon sugar), and attached to different parts of it a phosphate group and a nitrogenous base (either a purine or a pyrimidine).he monomers of DNA are deoxyribonucleotides, because their sugar is deoxyribose. The nucleotides in a nucleic acid are not all identical. There are four kinds in each nucleic acid, differing only in their bases. The bases in the nucleotides of RNA are cytosine, uracil, adenine, and guanine.
