Strongly express trp biosynthetic genes only the presence of high concentration of CAMP. the 15 The plant Coleus sometimes turns its leaves red. A hormone (here called "signal") is involved in the regulation of flowering and leaf color. A indicated pathway (see Figure 2) is hypothesized to explain its action. All members of a signal transduction pathway are shown. The T-bar symbols depicted in Figure 2 are consistent with the action of a protein that: a. removes a phosphate group and thereby inactivates its target proteins b. modifies nucleosomes and causes chromatin decondensation at its target gene adds a phosphate group and thereby activates its target protein d. binds the promoter of a gene, inhibiting RNA polymerase ll binding removes introns from RNA 16. The arrow symbol depicted in Figure 2 is consistent with the action of a protein that modifies nucleosomes and causes chromatin condensation at its target gene
Explanation / Answer
Answer 15.
Option: B :Modifies nucleosome and causes chromatin decondensation at its target gene
