Why is a chromosome with two centromeres (adicentric chromosome) unstable? Would a backup cen-tromere not be a good thing for a chromosome, giving ittwo chances to form a kinetochore and attach to microtu-bules during mitosis? Would that not help to ensure thatthe chromosome did not get left behind at mitosis?

Differentiate the processes of mitosis and meiosis. 2. Describe the role of mitosis in asexual reproduction, and/or the role of meiosis in sexual reproduction, including how these processes may contribute to or limit genetic variation. 3. Describe specific events occurring in each of the stages of the cell cycle and/or phases of mitosis. 4.

A female fruit fly has one normal X chromosome and one X chromosomewith a deletion. The deletion occurred in the middle ofthe X chromosome and removed about 10% of the entire length ofthe X chromosome. Suppose you stained and observed the chromosomesin salivary gland cells of this female fruit fly. Draw thepolytene arm of the X chromosome. Explain your drawing.

Explain. no, it wouldnt have the DNA OP 10. The S phase stands for synthesis, which means to make or build something more complex out of simpler parts. Scientists know that during the S phase DNA is being made in the nucleus of the cell. Why do you think the cell needs to make more DNA at this time in the cell cycle? 11. Refer to Model 1. The chromosomes that are shaped like "X" (made of two sister chromatids) have double the amount of DNA than the chromosomes that are shaped like "I."

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?
