The number of protein-encoding genes in a prokaryotic cell equals the number of proteins that can be expressed in
the same cell. However, a eukaryotic cell can express many more proteins than the number of protein-encoding
genes in the same cell. Why is this the case? Explain in one sentence only.
Create a Venn diagram to compare and contrast the process of gene expression in Bacteria versus eukaryotes. Remember that “gene expression” can include any part of transcription or translation. Try to be as thorough as you can about what aspects of this process are similar between the two taxa, and what characteristics are distinct to only Bacteria or eukaryotes. Plase include a minimum of 15 items in the Venn diagram.
name TWO mechanisms of control of gene expression that are only used by eukaryotes and discuss why each of those mechanisms wouldn’t be possible in prokaryotes.

- Which of the following best explains how the expression of a eukaryotic gene encoding a protein will differ if the gene is expressed in a prokaryotic cell instead of in a eukaryotic cell? No transcript will be made, because eukaryotic DNA cannot be transcribed by prokaryotic RNA polymerase. The protein will be made but will not function, because prokaryotes cannot remove introns. The protein will not be made, because prokaryotes lack the ribosomes necessary for translation. The protein will have a different sequence of amino acids, because prokaryotes use a different genetic code.arrow_forwardWith the aid of diagrams, and using specific examples, describe how gene expression is regulated in prokaryotes.arrow_forwardDiscuss the control of gene expression in eukaryotes. PLEASE KEEP IT SHORTarrow_forward
- What analogies can you draw between transcriptionaltrans-acting factors that activate gene expression in eukaryotes and the corresponding factors in bacteria? Givean examplearrow_forwardWHAT ELSE CAN I ADD TO THIS DISCUSSION In general, what is gene regulationand what are the consequences if this process goes awry? Gene regulation is the process used to control the timing, location and amount of genes expressed. The process is carried out by a variety of mechanisms, including regulatory proteins and chemical modification of DNA. It’s key to the ability of an organism to respond to environmental changes. If the gene regulation process goes awry, these alterations are called mutations and can accumulate over a lifetime. Errors in genes that control cell division can cause cancer and other genetic mutations to take place.arrow_forwardCompare and contrast (that means tell me how the are similar AND how they are different) gene regulation mechanisms in prokaryotes and eukaryotes. explain why regulation is more complex in multicellular eukaryotic organisms as compared to prokaryotic organisms by providing examples of eukaryotic gene regulation mechanisms (you don’t have to give me all the steps, just the concepts).arrow_forward
- A) List the steps for gene expression in prokaryotes and eukaryotes. B) Relate the differences in gene expression between prokaryotes and eukaryotes in gene expression regulation and explain what causes those differences.arrow_forwardSelect all the examples of mutations that are likely to have a global effect on gene expression. Check All That Apply a mutation in a splice donor recognition sequence within an snRNA gene a mutation that reduces expression of an rRNA a hypomorphic mutation in the catalytic site of RNA polymerase a silent mutation in a gene encoding a protein in the small ribosomal subunit a nonsense mutation in a gene encoding an ion channelarrow_forwardCompare the control of gene regulation in eukaryotes and prokaryotes at the level of initiation of transcription. How do the regulatory mechanisms work? What are the similarities and differences in these two types of organisms in terms of the specific components of the regulatory mechanisms?
