During the M-phase (Mitosis), spindle fibers extend from centrioles in the poles of the cell and attach to the centromeres of each replicated chromosome. The chromosomes are aligned along the equatorial plate of the cell in the process. Once all centromeres got attached from either side to a spindle fibre, a cellular checkpoint got passed and the spindle fibers begin to contract towards the poles, pulling the two sister chromatids apart such that one sister chromatid of each of the...

5. (16 pts.) A cell has two pairs of submetacentric chromosomes, which we wili cail chromosomes I,, Ib, Ila, and Ilb. Submetacentric chromosomes have their centro nere abou midway between the telomere and middle of the chromosome as shown. Chromosomes Ia and I, are homologues and chromosomes II, and Ilb are homologues. Allele R is located on the p arm (short arm) of chromosome of chromosome la, and allele r is located at the same position on chromosome lb. Allele...

Watermelons can have varying ploidies. Ploidy refers to the number of each chromosome present in a somatic cell. For example, most varieties are diploid that contains two copies of each chromosome, while some are tetraploid which contain four copies of each chromosome. Seedless varieties are triploid which have three copies of each chromosome that are present. Armed with the knowledge that seeds are plant embryos that have the potential to become a mature plant (and therefore are comparable to human...

EXERCISE GOAL Your goal is to record an image of a cell with metaphase chromosomes that are clear enough to count so that you can determine the ploidy level of your sample. Remember, that the Triticeae group are always n = 7, so your sample must be one of the following: 10n = 70 2n = 14 4n = 28 6n = 42 8n = 56 We were unable to transcribe this image1.
