What is the difference between the metaphase chromosome and telophase chromosome? O Metaphase chromosomes exist as single chromatids; meanwhile, telophase chromosomes appear as sister chromatids Metaphase chromosomes materialize as homologous chromosome; on one hand, telophase chromosomes are structurally bonded with its homologue. • Metaphase chromosomes are structurally bonded with its homologue; on the other hand, telophase chromosomes do not materialize homologous chromosomes. Metaphase chromosomes exist as sister chromatids; meanwhile, telophase chromosomes appear as single chromatids

TELOPHASE This stage shows the end of Telophase AFTER cytokinesis has occurred • Nuclear membrane reformed in each cell • Nucleolus reformed in each cell • Centrioles present in cells at one end Two new daughter cells with same # of chromosomes: 46 single stranded chromosomes in each nucleus Daughter Cell Diploid cell 2n = Daughter cell Diploid cell 2n =
• 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 icular places along the DNA molecule. Each chromosomes can have a thousand genes but we are focusing on these two.
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?
Ith the description: Homologous chromosomes line up in pairs along the metaphase plate. 1. Telophase II followed by cytokinesis Crossing over occurs between homologous chromosomes. 2. Metaphase I 3. Anaphase I| Four haploid, genetically unique cells are formed. 4. Prophase I Homologous chromosomes are separated. 5. Anaphase I Sister chromatids are separated. >

Hypothetically speaking, what will be the form of chromosomes if it will condense after S phase? O homologous chromosome OOOO sister chromatids Osingle chromatid telophase chromosome
Which of the following statements are true regarding mitosis in humans? 23 pairs of homologous chromosomes are separated four haploid gametes are produced in males 46 pairs of homologous chromosomes are separated two genetically identical daughter cells are produced 23 pairs of sister chromatids are separated 46pairs of sister chromatids are separated 1 haploid gamete and 2 polar bodies are produced in females
The checkpoint permits cell entry into mitosis only if all DNA is replicated.* Start APC/C G2/M G1/S A hydrogen atom is sometimes referred to as a proton because O It is positively charged It is negatively charged It has just one proton It has just one electron How many chromosomes are in a human sex cell right after meiosis I? * O 46 O 23 92 4 Which protein family is responsible for facilitating the process of programmed cell death that is activated in cells with significant DNA damage? * O Separase OCaspase Cdk-cyclin OShugoshin O O O O O O O O
Figure 10.6 Which of the following is the correct order of events in mitosis? Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the mitotic spindle. The nucleus reforms and the cell divides. Cohesin proteins break down and the sister chromatids separate. The kinetochore becomes attached to the mitotic spindle. Cohesin proteins break down and the sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus reforms and the cell divides.

Mitosis Meiosis Definition Prophase Metaphase Anaphase Telophase Prophase I Metaphase I Anaphase I Telophase I Prophase II Metaphase II Anaphase II Telophase II Steps of each phase Number of cell divisions Number of cells produced *How many chromosomes per 46 daughter cell? * Mitosis starts with 46 chromosomes in each parent cell, and then ends with 46 chromosomes in each daughter cell. Cells divide onl once in Mitosis, but they divide twice during Meiosis, so we should end with half as many chromosomes in Meiosis vs Mitosis.
Which key step happens during anaphase? Oreplication of chromosomal DNA in the nucleus condensation • separation of homologous chromosomes separation of sister chromatids of chromosomes into sister chromatids
