Cell Cycle and Mitosis

A collection of vocabulary flashcards defining key terms, durations, and concepts related to the cell cycle and mitosis from the transcript.

Interphase

The period between two cell divisions when the genetic material makes its copy so that it is equally distributed to the daughter cells during mitosis.

G1 phase

The linking period between the completion of mitosis and the beginning of DNA replication (Gap 1 phase) lasting $10.5\,hrs$, during which cell size increases.

S phase

The period of DNA synthesis (Synthesis phase) lasting $10.5\,hrs$, which leads to the duplication of chromosomes.

G2 phase

The time between the end of DNA replication and the beginning of mitosis (Gap 2 phase) lasting $3.5\,hrs$, during which cell organelles divide and prepare chromosomes for mitosis.

M phase

The cell division phase lasting $1\,hr$, which includes prophase, metaphase, anaphase, telophase, and cytokinesis.

Potu Narasimha Rao and Johnson

Researchers who conducted experiments using the cell fusion technique to reveal the structure of interphase chromosomes and provide evidence on cell cycle progression via freely diffusing chemical signals.

Cell fusion technique

An experimental technique combining two cells in experimental conditions to reveal interphase chromosome structures and analyze cell cycle progression.

Karyokinesis

The division of the nucleus during cell division.

Cytokinesis

The division of cytoplasm following karyokinesis, which finally brings about the formation of two daughter cells.

Prophase

The stage of mitosis where chromosomes condense, get coiled, and become visible.
