We know that dna and rna (each with four nucleotide components) both use a three nucleotide genetic code and 64 codons (43 = 64). knowing that the minimum number of codons for the genetic code is 21 (20 amino acids, 1 stop codon), what codon size would be required if only three nucleotides were present in the genome? a) 2 nucleotides per codonb) 3 nucleotides per codonc) 5 nucleotides per codond) 4 nucleotides per codone) 6 nucleotides per codon

Where is most of the fresh water on earth found a in the ocean b in glaciers and in ice caps c in rivers d in the soil

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
