The flower color of genetically identical hemp plants (clones) is purple when the flowers develop under cold environment (<14 °C) and white when they develop under hot environment (>30 °C). Describe in detail a molecular mechanism that could explain how these two groups of genetically identical plants differ in their gene expressions to produce different flower colors?

- Yes or no? during in situ hybridization for signal development the beta galactosidase is used.arrow_forwardDid your mutation actually disrupt binding? Please choose the best explanation based on what you calculated above. No, because the affinity for the mutant is higher than the affinity for the wild type. Yes, because the affinity for the mutant is lower than the affinity for the wild type. No, because the affinity for the mutant is lower than the affinity for the wild type. Yes, because the affinity for the mutant is higher than the affinity for the wild type.arrow_forwardLet’s suppose a researcher was interested in the effects of mutationson the expression of a protein-encoding gene for a proteinthat is 472 amino acids in length. This protein is expressed in leafcells of Arabidopsis thaliana. It has a molecular mass of approximately56,640 Da. Make a drawing that shows the expected resultsof a Western blot using proteins isolated from the leaf cells thatwere obtained from the following plants:Lane 1. A plant homozygous for a nonmutant geneLane 2. A plant homozygous for a deletion that removes the promoterfor this geneLane 3. A heterozygous plant in which one gene is nonmutant andthe other gene has a mutation that introduces an early stop codon atcodon 112Lane 4. A plant homozygous for a mutation that introduces anearly stop codon at codon 112Lane 5. A plant homozygous for a mutation that changes codon108 from a phenylalanine codon into a leucine codonarrow_forward
- What are the for phytoglycogen confirmation properties in maize can that can determine the extracted glycogen in the plants. Present it nicely.arrow_forwardA. The genes CLV3, CLV1/2 and WUS are involved in maintaining the size of shoot apical meristem. Diagram the interactions among these gene products, using ‘—>’ for positive interactions (i.e. activation) and ‘ —|’ for negative interactions (i.e. repression). B. What phenotype would you expect for a double mutant clv3 wus? And why?arrow_forwardE2F is a transcriptiion factor that activates genes for DNA rep- proteins. In addition with RBR, E2F is one of the controls for G1 to S transition. Why would E2F have a role in totipotyency of plant cells?arrow_forward
