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.
Describe how you would use replica plating of mutagenized, haploid yeast cells to identify temperature-sensitive (ts) mutations in essential genes needed for yeast growth and survival.

- Let’s say, you want to deliver a gene into a cell and in your lab, there are lot of options available to do that. Describe five different options that you can use to deliver that gene.arrow_forwardThe figure below shows RNA-Seq data (RED) for the D. melanogaster transformer (tra) gene obtained from both adult female and male fruit flies. The blue lines indicate the tra gene structure, with thicker lines indicating exons, and thin lines introns. The 5' end of the gene is on the left, and the 3' end of the gene is on the right. Based on these data, the most likely conclusion is: Males and females express identical isoforms of tra Males express more tra RNA than females The female isoform has fewer amino acids The female isoform has more amino acids The male and female isoforms have different 3'UTRsarrow_forwardin words or diagram explain how splicing can allow the same gene to encode different proteins of different lengths.arrow_forward

Mutation in the promoter that reduces the affinity of the promoter for RNA polymerase (P)? Mutation in the repressor gene such that the protein has lost the ability to bind allolactose (superrepressor mutant = I³)? Mutation in the repressor gene such that the protein has lost the ability to bind the operator (I)?

- Many aspects of gene function can be nicely explained with the one-gene-one-enzyme hypothesis, which states that a gene controls the production of an enzyme. Which of the following findings about gene expression, though, requires an expansion of this simple concept? Choose an answer below: Non-enzyme proteins are made from genes too. Some genes code for RNA molecules only. Enzymes composed of different polypeptides are coded for by more than one gene. a and c, but not b a, b, and carrow_forwardYou want to clone a eukaryotic gene and express the corresponding protein in yeast. However, the protein typically localizes within mitochondria. How will you perform your gene cloning so that the protein is secreted from the cell, rather than localized within yeast mitochondria?arrow_forward1. What is a gene? 2.
