Hi, could your please answer this question? I'm so confused. The following diagram (picture added) shows 2 pairs of autosomal chromosomes in a karyotype of a biological woman. Based on the karyotype, a genetic counselor determined that there is evidence that a translocation occurred between two non-homologous chromosomes. The other 21 pairs of chromosomes are NOT shown in this diagram. Assume no chromosomal aberrations occurred in the other chromosomes. As a student-researcher, what would be your answer if the genetic counselor asks you if you can determine whether the translocation occurred in a somatic cell, germ-line cell, or whether this can even be determined from the figure? provide the reasoning for your answer.
Select true or false for each of the following statements regarding metaphase I. Homologous chromosomes are connected only at the centromeres. Answertruefalse Homologous chromosomes are aligned at the metaphase plate. Answertruefalse The paternal chromosomes are aligned on one side of the metaphase plate and the maternal chromosomes are aligned at the other. Answertruefalse In a cell with 4 chromosome pairs, there are 16 different ways to align the tetrads. Answertruefalse Homologous chromosomes are independently assorted. Answertruefalse
Select true or false for each of the following statements regarding anaphase I. Sister chromatids remain attached at the centromeres. Answertruefalse Homologous chromosomes remain attached at the centromeres. Answertruefalse Sister chromatids are pulled apart. Answertruefalse Homologous chromosomes are pulled apart. Answertruefalse Chiasmata are broken. Answertruefalse
The cell above is a lung cell of a salamander. In which stage of mitosis is it? What are the structures visible in green and blue fluorescence?
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.
Need help with the diagram The STR DNA marker DS11 is located on the p arm of the chromosome #8 in humans. Molecular analysis has shown that Charlie Chaplin is a heterozygote for the STR marker (genotype DS11A and DS11B) Using this knowledge, provide a diagram of meiosis showing only the movements of chromosome 8 (assume no nondisjunction). Throughout, indicate where the marker may be found (in other words, label the chromosome to show where the STR markers can be found. please only show the chromosomes at interphase, metaphase 1, end of meiosis 1, metaphase 2, and end of meiosis 2.
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.
Please help Place the images of the cell division in the right order and label them a) What is the final product of this type of cell division? Indicate the number of dauahter cells, the TYPE OF CELLS (somatic cells? sex cells? other?), where in the body this process takes place, whether they are genetically diverse pridentical, haploid or diploid, the chromosome number in human cells, whether they contain sinale- or double-stranded chromosomes, and what the "fate" of these cells is i.e. what will they go on to do, if given the chance)?
please explain this in a length of a full page as much detail please 1.What are the primary functions of cell division (Mitosis) as compared to Meiosis, how are the daughter cells produced in each process different?
Identifying Processes On the lines provided, order the different stages of meiosis I THROUGH meiosis II, including interphase in the proper sequence. 1. _____________ homologous chromosome line up in the center of the cell 2.______________ spindle fibers pull homologous pairs to ends of the cell 3. _____________ 4 haploid (N) daughter cells form 4. _____________ cells undergo a round of DNA replication 5.______________ sister chromatids separate from each other 6. _____________ 2 haploid (N) daughter cells form 7.______________ spindle fibers attach to the homologous chromosome pairs 8. _____________ individual chromatids move to each end of the cell 9.______________ crossing-over (if any) occurs
Draw and label G1 and G2 stages of interphase and each stage of mitosis (in order) for a cell that has two large and two small chromosomes, 2n=4. For unreplicated chromosome draw a line ( / ) and for replicated chromosome draw an X. Since we are focusing on the DNA, you can skip drawing the nuclear membrane or spindle fibers. For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. Mark and label a place on one of the large chromosomes with the dominant allele of the “A” gene and put the recessive allele “a” on the other homolog. Mark and label a place on one of the small chromosomes with allele “B” and put the recessive allele “b” on the other homolog.
Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. (There needs to be a model drawing) What would a 2n=10 cell look like during prophase I? What would that cell look like during metaphase I? At the end of meiosis I? During metaphase II? At the end of meiosis II?
