You discover a novel unicellular, sexually reproducing organism. The ‘A’ (or ‘a’) locus is 38 map units away from the ‘B’ (or ‘b’) locus. Suppose that ‘A’ encodes cilia that help the cell to move (and is dominant to ‘a’ which is incapable of moving) and that ‘B’ encodes ability to perform photosynthesis (and is dominant to ‘b’ which is incapable of photosynthesis). The ‘A’ locus is on the same chromosome as the ‘B’ locus. One parent with the genotype...

You read an article in a popular magazine about a unicellular plant that has DNA with catalytic activity. Knowing that RNA can have catalytic activity, would you believe this article? A) Yes, all that is required is a 3’OH to attack the 3’splice site. B) No, uracil of RNA is required in the catalytic site. C) No, DNA is constrained by its double helix structure and could not fold into a catalytic structure. D) Yes, DNA could easily be attacked...
