What is replicated during mitosis?

This process involves replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm. … The outcome of binary fission is two new cells that are identical to the original cell.

Does chromosome replication occur in mitosis?

In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase). …

Which are replicated during interphase Brainly?

Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellularorganelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.

What is the function of the kinetochore during mitosis quizlet?

Kinetochores form the attachment between the sister chromatids and the dynamically growing and shrinking microtubules of the mitotic spindle. The kinetochores are also able to sense the tension formed when the two attached sister chromatids are properly attached to each pole of the bipolar spindle.

Which stage of mitosis includes kinetochore fiber formation?

In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles.

What is the function of the kinetochore microtubules in mitosis?

Microtubules that bind a chromosome are called kinetochore microtubules. Kinetochore fibers extend from the kinetochore region and attach chromosomes to microtubule spindle polar fibers. These fibers work together to separate chromosomes during cell division.

How is a chromosome replicated?

During the DNA synthesis (S) phase, the cell replicates its chromosomes. During the mitosis (M) phase, the duplicated chromosomes are segregated, migrating to opposite poles of the cell. The cell then divides into two daughter cells, each having the same genetic components as the parental cell.
