18. Based on the following nucleotide structure, answer the following questions: NH₂ a. O- b. O OH OH Is the base present in this nucleotide a purine or a pyrimidine? What is the abbreviation for the base present in this nucleotide? (A, T, C, G, U). c. Would the sugar in this nucleotide be found in molecules of DNA or RNA or both? d. Would the base in this nucleotide be found in molecules of DNA, RNA or both? -OCH₂
Coding Strand of DNA
When pointing to DNA transcription, the coding strand is found to be the DNA strand whose base sequence is indistinguishable from the base sequence of the RNA transcript developed. It is this strand that comprises the codons, while the non-coding strand comprises the anti-codons.
Nucleotide
Both DNA and RNA are composed of organic molecules known as nucleotides. Hence, nucleotides are known as the basic building blocks of nucleic acids. These substances play a role in various processes such as cell signalling, enzyme reactions, metabolism, and so on.
Structure of Cytosine
Cytosine is among the five primary nitrogenous bases of which DNA and RNA and are being used in storage and transportation of genetic makeup within a cell. Adenine, guanine, thymine as well as uracil are the remaining four nucleobases.
