- To which chromosome and which band does the sequence localise? Write the location in the standard format: e.g. 8q21.3, not Chr 8 (q21.3). *clone number in this case is 196 which is shown in the images*In an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of thehaploid fungus Neurospora crassa (n = 7) moves slowlybut eventually forms seven bands, which represent DNAfractions that are of different sizes and hence havemoved at different speeds. These bands are presumed tobe the seven chromosomes. How would you show whichband corresponds to which chromosome?When stained with Giemsa (G-Banding staining), the centromere will be stained: Question 28 options: more robustly (dark band) less robustly (light band)
- Giemsa stain produces G bands in metaphasechromosomes. The pattern of G bands is highly specificand reproducible, allowing identification of _____________-and gene locations.Bacterial and eukaryotic chromosomes are very compact. Discuss theadvantages and disadvantages of a compact chromosomal structure.Colchicine is a chemical mutagen that inhibits the spindle formation and prevents anaphase, which retains the cell’s single restitution nucleus (doubled chromosome number). Suppose that an onion (2n=16) is subjected to three consecutive rounds of colchicine treatment, what will be the resulting chromosome number of the treated onion?
- In an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of the haploid fungus Neurospora crassa (n = 7) moves slowly but eventually forms seven bands, which represent DNA fractions that are of different sizes and hence have moved at different speeds. These bands are presumed to be the seven chromosomes. How would you show which band corresponds to which chromosome?The completely synthetic yeast chromosome Syn IIIcontains a loxP site in the 3′ UTR of every gene thatis potentially nonessential to yeast survival. As youwill recall from Chapter 6, loxP sites are targets ofsite-specific recombination. The researchers who constructed Syn III included these loxP sites as a way to“scramble” the chromosome, meaning that parts ofthe chromosome could easily be deleted or rearranged.The goal of these investigations is to drive the evolution of Syn III so as to define a minimal genome thatcan support the life of this organism. Outline the experiment the researchers would do to scramble Syn IIIin order to define a minimal genome.. Genomes A, B, and C all have basic chromosomenumbers (x) of nine. These genomes were derivedoriginally from plant species that had diverged from each other sufficiently far back in the evolutionarypast that the chromosomes from one genome can nolonger pair with the chromosomes from any other genome. For plants with the following kinds of euploidchromosome complements, (i) state the number ofchromosomes in the organism; (ii) provide terms thatdescribe the individual’s genetic makeup as accurately as possible; (iii) state whether or not it is likelythat this plant will be fertile, and if so, give the number of chromosomes (n) in the gametes.a.

- With regard to the analysis of chromosome structure, explain theexperimental advantage that polytene chromosomes offer. Discusswhy changes in chromosome structure are more easily detected inpolytene chromosomes than in ordinary chromosomes.options for all 3 are euchromatin and heterochromatinIf you are comparing the two telomeres in each entryin the following list, in which cases would you expectthe two telomeres always to have exactly the samenumber of TTAGGG repeats?a. One telomere at one end of a chromosome, one telomere at one end of a nonhomologous chromosome.b. One telomere at one end of a chromosome, onetelomere at the corresponding end of the homologous chromosome.
