Which of the following statements are correct? Explain your answers. Centrosomes are replicated before m phase begins. Two sister chromatids arise by replication of the DNA of the same chromosome and remain paired as they line up on the metaphase plate. Interpolar microtubules attach end-to-end and are therefore continuous from one spindle pole to the other. Microtubule polymerization and depolymerization and microtubule motor proteins are all required for DNA replication. Microtubules nucleate at the centromeres and then connect to the kinetochores, which are structures at the centrosome regions of chromosomes.

Which of the following statements is TRUE? Group of answer choices a Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. b Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. c None of these are TRUE d Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome e Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin.

Please help Place the images of the cell division in the right order and label them a) What is the final product of this type of cell division? Indicate the number of dauahter cells, the TYPE OF CELLS (somatic cells? sex cells? other?), where in the body this process takes place, whether they are genetically diverse pridentical, haploid or diploid, the chromosome number in human cells, whether they contain sinale- or double-stranded chromosomes, and what the "fate" of these cells is i.e. what will they go on to do, if given the chance)?
During mitosis, the cohesin protein holds the sister chromatids together and is broken down by the ___________ protein. Shugosin protects cohesin from being broken down in the ________________ region until the anaphase stage when the sister chromatids separate. separase; centromere cyclin; centrosome H1 histone; heterochromatic shugoshin; nuclear ribobuclease; cytoplasmic
Define the following terms: a. chromosome b. chromatin
Draw and label G1 and G2 stages of interphase and each stage of mitosis (in order) for a cell that has two large and two small chromosomes, 2n=4. For unreplicated chromosome draw a line ( / ) and for replicated chromosome draw an X. Since we are focusing on the DNA, you can skip drawing the nuclear membrane or spindle fibers. For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. Mark and label a place on one of the large chromosomes with the dominant allele of the “A” gene and put the recessive allele “a” on the other homolog. Mark and label a place on one of the small chromosomes with allele “B” and put the recessive allele “b” on the other homolog.
The assembly and function of the mitotic spindle depend on numerous microtubule-dependent motor proteins. In the mitotic spindle, these motor proteins generally operate at or near the ends of the microtubules. Four major types of motor proteins are:
