Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

1. Peroxisomes are organelles surrounded by a single membrane. Soluble proteins that reside within peroxisomes are imported post-translationally, and they often contain the C-terminal tripeptide SKL (serine-lysine-leucine). a) How would you confirm that a C-terminal SKL tripeptide is a peroxisomal targeting signal? b) If cells were engineered to produce a hybrid protein consisting of a mitochondrial matrix protein (including its signal sequence) followed by a C-terminal SKL signal, where in the cell would you expect the hybrid protein to be found? Explain your reasoning.

10. In eukaryotic cells, glycosylation activity of membrane proteins is found in the lumen of the endoplasmic reticulum (ER) and is accomplished by the enzyme oligosaccharyl transferase (OST), which adds oligosaccharides to the amino group of Asn residues of the consensus sequence Asn-X-Thr/Ser. a. The following ER membrane protein construct has a cytosolic N-terminal region and a membrane-spanning variable sequence. The variable sequence is a signal anchor (SA) sequence.

An additional transmembrane region is added to the construct prior to the variable sequence, as shown below.

8. In genetic screens of mutagenized yeast, temperature sensitive mutants defective in the secretory pathway (sec mutants) were identified. These mutants have helped scientists study the protein secretion pathway that is necessary/essential for life in eukaryotic cells. To identify sec mutants: mutagenized yeast cells were grown for 12 hours at low temperature, shifted to higher temperature for two hours, and then the population of cells were centrifuged in a density gradient. a. Mutagenized cells were first grown at the lower temperature and then shifted to the higher temperature. i. Why was the shift in temperature an important step of the experimental protocol? ii. Why would the experiment have been unsuccessful if the cells were grown exclusively at the higher temperature? b. After centrifugation, where would sec mutant cells be located compared to other cells in the population? Briefly explain why.

1. Lysosomal hydrolases contain sorting signals that mark these proteins for modification with mannose 6-phosphate. Lysosomal sorting signals are unusual in that they are not peptides attached to the termini of the proteins. Instead, lysosomal sorting signals are “patches” on the folded proteins. Such a signal patch may include amino acids that are distant from one another in the linear polypeptide chain, but are brought close together by protein folding. When cell biologists identify a sorting signal, they confirm that the signal isnecessary and sufficient. Suppose that you have identified a putative signal patch on a lysosomal hydrolase. How would you test whether this signal is necessary and sufficient to mark the protein for modification with mannose 6-phosphate? 2.

39. What makes it possible for human mitochondria, which have only 22 sequences that code for tRNA, to translate mitochondrial polypeptides that require 32 tRNAs?
Transposable elements, “jumping genes”, were first described by Barbara McClintock in her Nobel prize winning studies with corn. The genome of every multicellular eukaryote that has been sequenced is composed of a large percentage of transposable elements (often 30% to 50%), but they are nearly absent from the genomes of eubacteria and archaea. What are these things and what do they do? Describe and draw the structural organization and mechanism for movement of transposons and retro- transposable elements. What effect do these elements have on the stability of genomes? can you help me answer the bolded question?
