Explain your choice.4s: Claire is examining a whitefish blastula cell under a microscope. Based on her observations, Claire proposes that the whitefish blastula cell is in interphase. Which of the following pieces of evidence would best support Claire’s claim? The genetic content of the cell exists as dispersed chromatin. The genetic content of the cell exists as dispersed chromatin. The mitotic spindle is fully assembled, with its poles at opposite ends of the cell. The mitotic spindle is fully assembled, with its poles at opposite ends of the cell. A cleavage furrow has formed on the cell’s surface. A cleavage furrow has formed on the cell’s surface.

- Explain the following terms: Non-histone Chromosomal (NHC) proteins, euchromatin & Heterochromatin.Decondensed chromatin, but not condensed chromatin can be remodeled. O is associated with methylation of CpG islands. O is often acetylated. 5 O is packed into nucleosomes.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.
- Re-write the following statement to make it true: "Mitotic CDK is absent when the cell is in interphase and is present only during mitosis."Match the type of chromatin with the chromosome structure or region. chromatin of telomeres v Choose... facultative heterochromatin constitutive heterochromatin chromatin of centromeres eychromatinHistone _______ is not part of the histone octamer, but binds to linker DNA and is responsible for higher-order chromatin structureA-H1B-H2AC-H4D-H3E-H2B
- options for all 3 are euchromatin and heterochromatinLess condensed region of an interplase chromosome that stains diffusely. Which one Beads on a string Heterochromatin Histone Euchromatin Octamer nucleosomeDraw 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.
