Step by step
Solved in 2 steps
![Blurred answer](/static/compass_v2/solution-images/blurred-answer.jpg)
- Since all cells contain the same number of chromosomes and the overall same/similar genome how would the genome in a nerve cell work differently than the genome of a muscle cell? In other words what epigenetic processes cause these differences between cell types at the molecular levelHow many copies of each type of core histone would it take to wrap the entire human genome into nucleosomes? How has evolution solved the problem of producing such a large number of proteins in a relatively short period of time?All the cells of one organism share the same genome. However, during development, some cells develop into skin cells while others develop into muscle cells. Briefly explain how the same genetic instructions can result in two different cell types in the same organism.
- When the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in the human cells that there are different genes in the genome. How can this be explained?Acquired mutation in the p53 gene is the most common genetic alteration found in human cancer (> 50% of all cancers). A germline mutation in p53 is the causative lesion of Li- Fraumeni familial cancer syndrome. In many tumors, one p53 allele on chromosome 17p is deleted and the other is mutated. What type of protein is encoded by the p53 gene? (A) Caspase (B) DNA repair enzyme (C) Membrane cell adhesion molecule (D) Serine phosphatase (E) Telomerase (F) Transcription factor (G) Tyrosine kinaseWhy would a mutation in a somatic cell of a multicellular organism not necessarily result in a detectable phenotype?
- If you were to design an experiment to get p53 back into cancer cells, how would you go about that work? How would you direct p53 into the nucleus of cancer cells without directing it to the nucleus of healthy cells? As an overabundance of p53 in healthy cells would cause problems. Could someone in depth answer these questions for me and explain them cellularly.Chromosomes pass genetic information from one cell to another in cell generation. (j) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information. (k) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.Consider Molecule X, which is found in all living cells. This molecule is transcribed from a stretch of DNA in the nucleus. Each nucleobase on the DNA produces a matching nucleobase on this molecule. Every 3-base codon specifies an amino acid in a protein. What is the name of X? Your answer should be one word, or a short two- or three-word phrase. Spelling counts. Note: if there is more than one possible answer, separate each answer with a comma. x 5
- Not long ago investigators were surprised to learn that more than 95% of a mammalian genome is transcribed, even though less than 2% encodes proteins. What kind of evidence could be used to determine the percentage of the genome that is transcribed?Antibiotics such as chloramphenicol, tetracycline, and erythromycin inhibit protein synthesis in bacteria, but have no effect on the synthesis of proteins encoded by eukaryotic nuclear genes. Cycloheximide inhibits the synthesis of proteins encoded by nuclear genes, but has no effect on bacterial protein synthesis. How might these compounds be used to determine which proteins are encoded by mitochondrial and chloroplast genomes?(a) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information. (b) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.
