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.
There are four nucleotides that make up DNA: Adenine, Thymine, Guanine and Cytosine. There are billions of them that make up one strand of DNA. Adenine always pairs with Thymiâ¦ne and Guanine always pairs with Cytosine. Also, in the Rna during DNA transcription, Uracil replaces Thymine and pairs with Adenine instead.
