Solved in 3 steps
- What type of chromosome (metacentric, submetacentric, acrocentric, or telocentric) is chromosome 1? What about chromosome 4?Describe the basic anatomy of a condensed chromosome, including its centromere, telomeres, arms and sister chromatids.What structures are found in a chromosome? Group of answer choices Two structures for the mitotic spindle to bind, and two complex repetitive structures that are maintained by telomerase One structure for the mitotic spindle to bind, and two complex repetitive structures that are maintained by telomerase One structure for the mitotic spindle to bind, and one complex repetitive structure that is maintained by telomerase Two structures for the mitotic spindle to bind, and one complex repetitive structure that is maintained by telomerase.
- Metacentric chromosomes have a centromere located: A. near the middle of the chromosome (chromosome has two arms of approx. equal length) B. towards one end (chromosome has one long arm and one short arm) C. near one end of the chromosome (chromosome has one long arm and a knob at the other end)What are Dicentric chromosome ?Chromosome study requires visualization of metaphase chromosomes, how do we achieve this?
- ● ● Illustrate the chromosome changes in interphase and mitosis using a diploid cell that is 2n=4 (two large and two small chromosomes). Label the circles as G1 and G2 stages of interphase and each phase of mitosis (in order). Draw the chromosome in each circle using the following guidelines. 1) For unreplicated chromosome draw a line (/) and for replicated chromosome draw an X. 2) For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. 3) Skip drawing the nuclear membrane or spindle fibers, since we are focusing on the chromosomes. Label genes in the resulting daughter cells as A/a and B/b. (These letters represent genes which are at particular places along the DNA molecule. Each chromosomes can have a thousand genes but we are focusing on these two.) Ask me Qs in class if anythign on this is not clear.Can you please Draw what this should look like. Chromosome Model Procedure for making a solid wire model of a chromosome: 1. Get 4 solid wires, 2 long ( 1 green and 1 red ), 2 short ( 1 green and 1 red ). This will represent 4 chromatins of a The wires of the same size are homologous. Red wire will come from the female and green wire from the male. Long green : 1a Long red : 1b Short green : 2c Short red : 2d 2. Let the cell pass the S phase. Replicate or duplicate each chromatin Do this getting another set of wires identical to the original set. Label as before. 3. Join the replicated chromatin fiber using a tape. The tape will also mark the position of the centromere. For the short chromatin, place the tape exactly at the center, while for the long chromatin, place it at ¾ from the end of the wire. This will now represent the chromosomes.puey drganlsm yo are working with has the following chromosomes. Place the chromosomes of this organism onto the cell below such that the diagram accurately shows a cell from this organism in metaphase of mitosis. Note 1: Only place chromosomes you need. You don't need them all. Note 2: You can place the 'Blank Box' image if you don't think you need a chromosome at a particular position. Dashed line - the metaphase plate 1.
