WS15 MM

Instructions: Draw the images asked for. Given a hypothetical cell with ploidy 2n = 6, draw the chromosomes as they move through the different stages of mitosis and meiosis. The colors of the chromosome represent a pair of homologous chromosomes. Please include the colors of the chromosomes in you drawings. Solutions to questions in this portion of the module are found in the university learning management system. In

Please help me on question 5 and 6

Asap

Discussion 1 pts Meets Standards A complete and accurate description of the difference between sister chromatids and homologous chromosomes is provided. Accurate definitions for sister chromatids and homologous chromosomes are provided.

I need the answer as soon as possible

Please atleast answer this question   ?

please help

What is the correct answer?

Please help a. How many chromosomes and/or sister chromatids do Figure A and B show? b. What is the name of the process that took place to get from structure A to structure B?

Need help with question: -If a nucleus has 12 chromosomes during interphase,how many chromosomes does it have during metaphase? How many are there after mitosis has finished? - the contrast of the cleavage furrow with the cell plate. Offer details at the cellular level.

Please help me with question 7

Task: Show your work/explain your reasoning as much as possible.  Grading Criteria:  I want the correct answer and I want to see your work or read an explanation of your reasoning.  Question: If a certain species has a DNA content of 5 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a diploid cell (from the same species) in mitotic prophase? Explain your reasoning.  Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.

All the DNA in a cell is called its [Choose] Choose] Material of chromosome, a complex of DNA ani protein is referred as sister chromatids These nonreproductive cells or body cells are called somatic cells gametes This duplicated chromosome attached along thcir lengths by centromere cohesins. each contain two cell division This is the narrow "waist" of the duplicated chromosome where the two sister chromatids are attached. chromatin genome

svnapsis and tetrad chiasma formation recombined arrangement during during crossing over chromatids formed in prophase I in prophase I anaphase I PRACTICE PROBLEMS AND REVIEW QUESTIONS 1. How does metaphase of mitosis differ from metaphase I of meiosis? 2. During mitosis, a cell with 52 chromosomes will produce daughter cells with how many chromosomes? During metaphase I of meiosis you observe a cell with 84 chromatids. chromosomes will there be in the cells at the completion of meiosis? How many 3. When, during the life of an organism, would you expect to find the most intensive mitotic activity? 4. Describe a chiasma. When are they formed? What is the end result of the formation of chiasma? 5. What is the benefit of the genetic variation created during meiosis as it pertains to environmental pressures and the process of natural selection? 6.

Task: Show your work/explain your reasoning as much as possible.   If a certain species has a DNA content of 12 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a triploid cell (from the same species) in mitotic prophase? Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.

Question: How chromatids and centromeres are connected together? N.B: Which substance is responsible for the bonding of chromatids and centromeres. Don't Answer like this:Due to continuous dehydration nuclear chromatin condenses to form visible thread like structure, known as chromosome. Then each chromosome divides longitudinally into two chromatid. The sister chromatids are joined together at their centromere.

Please explain and help with details, thank you!
