Select the best process listed below for each of the following statements. Note that you need to know that the sequence of amino acids directly reflects the sequence of genes that coded for their placement.
A. Homologous sets of genes ABCDEF and AEDCBF are located on homologous chromosomes. B. A small region of a protein from three species is sequenced and found to be as follows:species X is alanine, glycine, glycine, threonine, alaninespecies Y is alanine, glycine, threonine, alaninespecies Z is alanine, glycine, glycine, threonine, alanineThe difference in the amino acid sequence of species Y is most likely due to this. C. The nucleotide sequences of homologous regions of DNA of two species are AATGCCCCGTTA and AATGCCCCGCTTA. If this is not the result of a nucleotide base-pair addition, then it is most likely the result of this. D. E. Homologous sets of genes ABCDEF and aBCdEF are located on nonhomologous chromosomes. Crossing over between them is suppressed because their locations are the result of this. F. Homologous sets of genes ABCDEF and ABCDEF are located on nonhomologous chromosomes. G. A small region of a protein from three species is sequenced and found to be as follows:species X is alanine, glycine, threonine, alaninespecies Y is alanine, glycine, threonine, alaninespecies Z is alanine, valine, glycine, threonine, alanineThe difference in the amino acid sequence of species Z is most likely due to this.
