8. Using recombinant DNA techniques (which willbe described in Chapter 9), it is possible to take theDNA of a gene from any source and place it on achromosome in the nucleus of a yeast cell. Whenyou take the DNA for a human gene and put it into ayeast cell chromosome, the altered yeast cell canmake the human protein. But when you remove theDNA for a gene normally present on yeast mitochondrial chromosomes and put it on a yeast chromosome inthe nucleus, the yeast cell cannot synthesize the correctprotein, even though the gene comes from the sameorganism. Explain. What would you need to do to ensurethat such a yeast cell could make the correct protein?

1pt A geneticist is comparing a sequence of nitrogen bases from a child's DNA to the same sequence in his father's DNA. The DNA sequences are shown below.. Use the evidence to determine whether a mutation has occurred in the child's DNA, and if so, interpret that mutation. Father's DNA: GGCTATC; Child's DNA: GGCTATC O A. No mutation has occurred to the DNA sequence. O B. A nitrogen base has been deleted from the DNA molecule. O C. A nitrogen base has replaced another nitrogen base in the DNA molecule. O D. A nitrogen base has been added to the DNA molecule.

2. Null mutations are valuable genetic resources becausethey allow a researcher to determine what happens to anorganism in the complete absence of a particular protein. However, it is often not a trivial matter to determinewhether a mutation represents the null state of the gene.a. Geneticists sometimes use the following test forthe nullness of an allele in a diploid organism: If theabnormal phenotype seen in a homozygote for theallele is identical to that seen in a heterozygote(where one chromosome carries the allele in question and the homologous chromosome is known tobe completely deleted for the gene) then the alleleis null. What is the underlying rationale for thistest? What limitations might there be in interpreting such a result?
