In Fig 11.3 on p 202 of your book, you are shown the various stages at which the expression of genes can be regulated. Notice that these different types of gene regulation occur within the nucleus or in the cytoplasm: Gene Regulation
|Packaging of DNA Transcription of a gene Processing of RNA Exit of RNA from the nucleus||Breakdown of the RNA message Translation of the mRNA Modification of the polypeptide Breakdown of the protein|
1. In general, what is gene regulation and what are the consequences if this process goes awry?
2. Select two types of regulation (see above for a list); one that occurs in the nucleus and one that occurs in the cytoplasm and briefly explain each process.
1. Briefly explain what this genetic code is in general and how it works.
2. What is meant by the universality of the genetic code?
3. Explain briefly what the advantages and disadvantages of this type of genetic code are to humans.
