Now that you have identified the sequence of the daughter strand based on the sequence on the parent strand, can you come up wit
h an equation that explains the relative proportions of each base in a DNA macromolecule? (Note that in the equation below, "G" represents the percentage of bases that are guanine, "T" represents the percentage of bases that are thymine, "A" represents the percentage of bases that are adenine, and "C" represents the percentage of bases that are cytosine.)
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.
Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.
DNA stores all of an organism’s genetic information. Its molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine.
These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule ;
cytosine and thymine are formed from pyrimidines- N at position 1 and 3 of a fused ring;
Guanine and adenine are formed from organic compounds called purines (pyramidines fused to another organic ring of imidazole.
Each base pair contains a purine and pyrimidine joined via hydrogen bonding e.g. A-T & G-C and are called base complements.
The resulting geometric arrangement allows for the formation of the DNA helix or spiral.
They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, ... However, there are radiometric dating methods that can be used on sedimentary rock, including luminescence dating
