Solved in 2 steps
- 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?What is somatic hybridisation? Describe the various steps in producing somatic hybrids from protoplasts. Mention any two uses of somatic hybridisation.What is “translocation”? Why it is essential for plants.
- Why plants derived from protoplast culture are named as somatic hybrids?Explain why crops such as bananas, seedless watermelons, and potatoes are mutants After irradiating wild-type cells of Neurospora (a haploid fungus), a geneticist finds two leucine-requiringauxotrophic mutants. He combines the two mutants ina heterokaryon and discovers that the heterokaryon isprototrophic.a. Were the mutations in the two auxotrophs in the samegene in the pathway for synthesizing leucine or in twodifferent genes in that pathway? Explain.b. Write the genotype of the two strains according toyour model.c. What progeny and in what proportions would youpredict from crossing the two auxotrophic mutants?(Assume independent assortment.)
- The flower color of genetically identical hemp plants (clones) is purple when the flowers develop under cold 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?Suppose we are studying the genes psbA (which codes for D1), DICER1 (which nonspecifically splices mRNA transcripts), and CYCLASE1 (which codes for a protein involved in apoptosis) in plant X. Which of the following would need to occur in the cytoplasm of plant X’s leaf cell to decrease the rate of photosynthesis? Inactivation of the psbA gene. Degradation of DICER1 mRNA transcripts in the cytoplasm. Increase the amount of P680+ Increase expression of CYCLASE1. a) 1,2and3 b) 1and3 c) 2and4 d) 4 only e) All of 1, 2, 3, and 4 are correctAccording to data from genome sequences, cytoplasmic dynein is absent in some plants (e.g.,Arabidopsis) and present in others (e.g.,rice).Does this finding surprise you? What else might you do to confirm or refute such a statement? How is it possible that higher plant cells could operate without cytoplasmic dynein?
