Provide an explanation as to why this is the case and what are the effects of this higher mutation rate of mitochondrial DNA on disease processes?arrow_forwardDescribe how oocyte nuclear transfer can be used toprevent the transmission of mitochondrial disease.arrow_forwardOnly 37 of the proteins in mitochondria are encoded by the mitochondrial DNA. The other proteins are encoded in nuclear DNA, then translated and transported to the mitochondria. Describe one unique feature of protein transport across mitochondrial membranes.arrow_forward
- What would most likely happen if the NLS signal sequence was removed from a protein that still contained a mitochondrial localization sequence and an SRP signal sequence? a) The protein would localize to the nucleus b) The protein would be retained in the ER c) The protein would localize to the mitochondria d) The protein would remain in the cytoplasm e) The protein would be secreted from the cellarrow_forwardIn Xenopus, one of the substrates of mitotic CDKs is the phosphatase Cdc25. When phosphorylated by mitotic CDKs, Cdc25 is activated. What is the substrate of Cdc25? How does this information help to explain the rapid rise in mitotic CDK activity as cells enter mitosis?arrow_forwardExplain a mechanism for how a nuclear-encoded protein is targeted to the inner membrane of the mitochondrion. Explain the mechanism for how a nuclear-encoded protein is targeted to the thylakoid membrane. Describe an experiment that could be conducted to show that there is a targeting system for a nuclear encoded protein that ultimately finds its way to a specific organelle.arrow_forward
- The biogenesis of functional mitochondria is dependent upon the products of both nuclear and mitochondrial genes, which poses several regulatory and logistical issues. Interestingly, many of the nuclear genes encoding mitochondrial proteins are regulated at the transcriptional level by Myc (activates transcription) and p53 (often represses transcription). Does this make sense? Why or why not?arrow_forwardExplain the action of the mitochondrial uncoupling proteinarrow_forwardDescribe an experiment that shows if early mouse embryo inner cell mass cells containing mitochondrial defects die through necrosis of apoptosis.arrow_forward
