1. The part of the cell cycle where DNA is duplicated inside the nucleus in preparation for cell division?

2. Most of the cell's life cycle spent in which phase?

3. During this part of the cell cycle phase, no nuclear envelope is visible and chromosomes align in the center of the cell and attach the the spindle by their centromeres?

4. Chromosomes are separated and pulled apart during this period of the cell cycle?

Expert Solution

Question 1

Answer: Cell cycle is process during which cell divides to form daughter cells. It involves three stages such as interphase, mitotic phase and cytokinesis. During S-phase of the interphase of cell cycle, DNA is duplicated inside the nucleus and prepare the cell for division.

Question 2

Answer: Most of the cells life cycle is spent in Interphase of the cell cycle. During this period cells grows by duplicating it's DNA and synthesizing all the proteins essential for cell division.

Question 3

Answer: During metaphase of the cell cycle, nuclear envelope is completely lost and the chromosomes align on the centre of the cell forming metaphase plate. The spindle apparatus that binds to kinetochore of the chromosomes cause the chromosomes to align in the centre of the cell.

Question 4

Answer: During anaphase of the cell cycle, chromosomes gets separated due to breakdown of cohesin between sister chromatids. The separated chromosomes are pulled to opposite sides of the cell.

The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell.

The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell.For example, consider these two proteins:1. Phosphofructokinase (PFK) is an enzyme that functions in the cytoplasm duringglycolysis.2. Insulin, a protein that regulates blood sugar levels, is secreted from specializedpancreatic cells.Assume that you can track the cellular locations of these two proteins from the time that translation is complete...
