Webif Z = X – Y, the order of genes is A-C-B; if Z = Y – X, the order of genes is B-A-C. In the example (Fig. 8-18), the recombination value C-Wx (21.7%) is nearly equal to … WebA gene is a discrete sequence of DNA nucleotides. DNA and proteins are key molecules of the cell nucleus. One gene makes one protein. A gene is made of DNA. Bacteria and viruses have DNA too. The DNA molecule is shaped like a twisted ladder. A half DNA ladder is a template for copying the whole. RNA is an intermediary between DNA and protein.
