I. In humans, chromosome 16 sometimes has a heavilystained area in the long arm near the centromere. Thisfeature can be seen through the microscope but has noeffect on the phenotype of the person carrying it.When such a “blob” exists on a particular copy ofchromosome 16, it is a constant feature of that chromosome and is inherited.A couple conceived a child, but the fetus hadmultiple abnormalities and was miscarried. When thechromosomes of the fetus were studied, it was discovered that it had three copies of chromosome 16 (it wastrisomic for chromosome 16), and that two of thethree chromosome 16s had large blobs. Bothchromosome 16 homologs in the mother lacked blobs,but the father was heterozygous for blobs. Which parent experienced nondisjunction, and in which meioticdivision did it occur?
You are given a metaphase chromosome preparation (a slide)from an unknown organism that contains 12 chromosomes.Two that are clearly smaller than the rest appear identical inlength and centromere placement. Describe all that you canabout these chromosomes.
During mitosis, the cohesin protein holds the sister chromatids together and is broken down by the ___________ protein. Shugosin protects cohesin from being broken down in the ________________ region until the anaphase stage when the sister chromatids separate. separase; centromere cyclin; centrosome H1 histone; heterochromatic shugoshin; nuclear ribobuclease; cytoplasmic
Mitosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of mitosis. Make sure to draw the alleles for genes A and B on the chromatids in every stage. For mitosis, remember that many events are going on in the cell that are relevant besides just the movement of chromosomes, so please fill in the cell with pertinent structures such as centrioles and spindles.
The centromere Group of answer choices A is a group of proteins that attach to the kinetochore. B is not present on the chromosomes of the daughter cells until anaphase. C is a region of DNA where sister chromatids associate with one another and where the kinetochore forms D is a group of proteins that attach to the mitotic spindle. E is a region of DNA where sister chromatids associate with one another
Paired homologous chromosomes (the tetrad) separate from one another and move towards opposite poles during: Select one: a. Anaphase II b. Anaphase I c. prophase I d. G1
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 the eukaryotic nucleus during interphase, a strand of chromatin consisting of eight conserved histone proteins, and a short region of double-stranded DNA wrapped around them, is: A. properly referred to as the radial miniband B. properly referred to as the supersolenoid C. properly referred to as the chromosome D. properly referred to as the nucleosome E. properly referred to as the solenoid
A colleague e-mails you saying that she has identified an interesting chromosome variation at 21q13. In discussing this discovery with a friend who is not a cytogeneticist, explain how you would describe this location, defining each term in the chromosome address 21q13.
A cell from a human female has just undergone mitosis. For unknown reasons, the centromere of chromosome 7 failed to divide. Describe the chromosomal contents of the daughter cells.
Variations in Chromosome NumberAneuploidy Describe the process of nondisjunction and explain when it takes place during cell division.
Figure 7.2 If a mutation occurs so that a fungus is no longer able to produce a minus mating type, will it still be able to reproduce? Figure 7.2 (a) In animals, sexually reproducing adults form haploid gametes from diploid germ cells. (b) Fungi, such as black bread mold (Rhizopus nigricans), have haploid-dominant life cycles. (c) Plants have a life cycle that alternates between a multicellular haploid organism and a multicellular diploid organism.
