Which of the following statements are true? Cells cannot begin mitosis until DNA replication is completed In haploid and diploid cells undergoing mitosis, homologous pairs separate into different daughter cells The products of meiosis in humans (sperm and eggs) typically contain 23 non-homologous chromosomes, each chromosome is comprised of a double helix. The products of mitosis in humans (daughter cells) typically contain 46 chromosomes total (23 homologous pairs), each chromosome is comprised of one double helix.

An organism with two of each kind of chromosome is said to be: (3) tetraploid (1) haploid (2) diploid (4) polyploid. In multicellular organisms, mitosis results in: (1) reproduction (2) growth and repair (3) sperm and egg production (4) fertilization. If an organism produced an egg that had 20 chromosomes, the body cells of that organism should have: (1) 10 chromosomes (2) 20 chromosomes (3) 30 chromosomes (4) 40 chromosomes. 11) is what helps us grow and is why we are all unique!

Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction. Use the diagram to identify one similarity and one difference between mitosis and meiosis.

A diploid cell (2n3D10) contains different types of chromosomesbased on the position of their centromeres Two chromosomes are found to be metacentric, while two chromosomes are acrocentric. Four are observedto have their centromeres submedially located while the remaining chromosomes have terminal centromeres. Illustrate the cell being described. Assuming the cell underwent cell division, drawthe appearance of the cell during the specified stages below a. Metaphase b. Anaphase c. Metaphase l d. Anaphasel e. Anaphase I| f. Telophase |
A eukaryotic cell is diploid and contains 10 chromosomes (5 ineach set). In mitosis and meiosis, how many daughter cells will beproduced, and how many chromosomes will each one contain?
Which type(s) of cell division (mitosis, meiosis I,meiosis II) reduce(s) the chromosome number byhalf? Which type(s) of cell division can be classifiedas reductional? Which type(s) of cell division can beclassified as equational?
What is the difference between the metaphase chromosome and telophase chromosome? 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 exist as sister chromatids; meanwhile, telophase chromosomes appear as single chromatids Metaphase chromosomes are structurally bonded with its homologue; on the other hand, telophase chromosomes do not materialize homologous chromosomes.
Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur. chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occurs
A sexually reproducing organism has the following phenotype DdEeAaTt. The D and E loci are on the same arm of a metacentric chromosome in the cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. There are no other chromosomes. Show a diagram of the cell in metaphase of mitosis and the result of mitosis.
Why is a chromosome with two centromeres (adicentric chromosome) unstable? Would a backup cen-tromere not be a good thing for a chromosome, giving ittwo chances to form a kinetochore and attach to microtu-bules during mitosis? Would that not help to ensure thatthe chromosome did not get left behind at mitosis?
HOW DO WE KNOW? how chromosomes are distributed during cell division, both in dividing somatic cells (mitosis) and in gamete- and spore-forming cells (meiosis). We found many opportunities to consider the methods and reasoning by which much of this information was acquired. How do we know that mitotic chromosomes are derivedfrom chromatin?
