- which of the following is not true about mitosis? a.) chromosomes line up in metaphase by connecting to kinetechore proteins b.) the process starts out as a diploid cell c.) dna replicates in M phase d.) cells can be 4n if cytokenisis does not occur at the endarrow_forwardDefine and discuss these terms: sister chromatidsarrow_forwardThe role of cohesin is toa. make chromosomes more compact.b. allow for the replication of chromosomes.c. hold sister chromatids together.d. promote the separation of sister chromatids.arrow_forward
- A parent cell divides to form two genetically identical daughter cells in the process of mitosis. For mitosis to take place: A. the parent cell must divide its DNA in half so each daughter cell gets only the genes needed to carry out its functions. In this way, differentiation occurs. B. the parent cell must reproduce its DNA during telophase C. the parent cell must first be fertilized D. the parent cell must replicate its entire genome prior to mitosis E. crossover must be delayed until the second cell divisionarrow_forwardB. If a gamete of an unknown animal species has 44 chromosomes, how many of each of the following structures will be present? 5. chromatids at anaphase I 6. chromatids at telophase II 7. centromeres after telophase I 8. centromeres after prophase II 9. chromosomes after anaphase II 10. chromosomes at metaphase Iarrow_forwardFor below problem, consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. Each pair contains a maternal and a paternal member (e.g., Am and Ap). Using these designations, demonstrate your understanding of mitosis and meiosis by drawing chromatid combinations as requested. Be sure to indicate when chromatids are paired as a result of replication and/or synapsis. You may wish to use a large piece of brown manila wrapping paper or a cut-up paper grocery bag for this project and to work in partnership with another student. We recommend cooperative learning as an efficacious way to develop the skills you will need for solving the problems presented throughout this text. Question: Assume that each gamete resulting from Problem 29 fuses, in fertilization, with a normal haploid gamete. What combinations will result? What percentage of zygotes will be diploid, containing one paternal and one maternal member of each chromosome pair?arrow_forward

For each of the following stages, state the number of chromosomes and the number of DNA molecules found in these chromosomes that are present in a human cell. a) Metaphase of mitosis Metaphase I of meiosis c) Telophase of mitosis (after cytokinesis)arrow_forward
- Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is eliminated, resulting in a diploid offspring.The process that produces the sperm and egg, and the process the offspring use to grow into adults are, respectively, Select one: a. Process to produce sperm and egg Process used for growth of the offspring Mitosis Cytokinesis b. Process to produce sperm and egg Process used for growth of the offspring Mitosis Meiosis c. Process to produce sperm and egg Process used for growth of the offspring Meiosis Cytokinesis d.
