Imagine that you have a device that can accurately measure the DNA content of individual cells of living yeast. This device enables you to do artificial selection on the genome size of the yeast. Propose an experiment using artificial selection that could test the hypothesis that the yeast genome size is optimal for yeast fitness versus the alternative hypothesis that transposons have caused the genome to evolve to a size that is larger than what maximizes yeast fitness.

Step 1
First, we need to obtain a large and diverse population of yeast cells with varying genome sizes. This can be achieved by isolating yeast cells from different environments or by inducing mutations in a laboratory strain. Show more…

In yeast, you have sequenced a piece of wild-type DNA and it clearly contains a gene, but you do not know what gene it is. Therefore, to investigate further, you would like to find out its mutant phenotype. How would you use the cloned wild-type gene to do so? Show your experimental steps clearly. Please do a step by step process

You put a human gene into a yeast cell to be expressed. Because yeast are eukaryotes, you expect everything to be fine. But then, some of your yeast begin making protein that is way too long! You sequence their DNA, and you find a mutation. Which of the following mutations could have caused the protein to be too long? Choose all that apply. A mutation that caused RNA polymerase to keep going after it normally stops A mutation that changed a STOP codon to a non-STOP codon A mutation that prevented splicing from occurring at a particular location None of the above

Expression of recombinant proteins in yeast is an important tool for biotechnology companies that produce new drugs for human use. In an attempt to get a new gene X expressed in yeast, a researcher has integrated gene X into the yeast genome near a telomere. Will this strategy result in good expression of gene X? Why or why not?
