Question
Chapter 9, Problem 6FIB
Summary Introduction
Introduction:
A chromosome is a DNA molecule with all the genetic material. It is a thread like structure present in the nucleus in coiled form around a protein called histone that supports its structure.

which of the following would indicate that a cell is in metaphase?
Thin, threadlike chromosomes are widely dispersed in the nucleus.
Chromosomes appear as dark granules in the nucleus.
Centromeres of chromosomes lie on the equator of the cell.
Two sets of chromosomes are present on opposite poles of the cell.
You view a mature, living plant cell such as an epidermal cell under the light microscope. You view the cell at sufficiently-high magnification and you have also stained the cell for chromatin. The cell has a nucleus, yet you cannot see chromosomes, at least in their typical ’sausage-formed’ shape as we all know them from textbooks. Why is that?
Which of the following statements regarding microtubules is FALSE?
Microtubules are typically arranged in cells such that thoir plus (+) ends are directed towards the plasma membrane and their minus (-) ends are
attached to the centrosomes.
Microtubules are composed of 13 protofilaments that are arranged into a hollow cylinder.
Microtubules are polar.
Microtubule-binding proteins, such as Tau, bind to microtubules to destabilizo thom.
Microtubules are inherently unstable and rapidly disassemble with low/ GTIP concentrations.

It binds tightly to microtubules and stabilizes them. When added to cells, it causes much of the free tubulin to assemble into microtubules. Taxol can be used as an anticancer drug.

Be specific.arrow_forwardEven though cytokinesis is included with Mitosis, we generally consider it to be its own phase. Why? by the time cytokinesis occurs, the cell has already split by the time cytokinesis occurs, the cytoplasm has already split by the time cytokinesis occurs, the nucleus has already split by the time cytokinesis occurs, the cell has copied all of its chromosomesarrow_forward
