3 MAJOR PHASES OF CELL CYCLE
NON-DIVIDING PHASE
INTERPHASE
DIVISION
3 MAJOR PHASES OF CELL CYCLE
- The resting quiescent phase
NON-DIVIDING PHASE
3 MAJOR PHASES OF CELL CYCLE
- Initial growth, DNA synthesis, and Final growth phase.
INTERPHASE
3 MAJOR PHASES OF CELL CYCLE
- Mitosis and Meiosis
DIVISION
- Coiled chromatin of new daughter cells.
QUIESCENT PHASE
- Uncoiling chromatins
INTERPHASE (G1)
- Pairing of homologous chromosomes.
PROPHASE
- Alignment of chromosomes in the middle plate.
METAPHASE
- Separation of sister chromatids.
ANAPHASE
- Separation of cytoplasm or cell wall.
TELOPHASE
- Uses he term chromatin because there are no homologous pairs with no centromere.
INTERPHASE (G1)
STAGES OF INTERPHASE
INITIAL GROWTH STAGE
DNA REPLICATION STAGE
FINAL GROWTH STAGE
STAGES OF INTERPHASE
- Increase protein (ribosome) production to be used for DNA replication. There are no observable changes in cell appearance but increased metabolic activities with minimal death in cells.
INITIAL GROWTH (G1) STAGE
STAGES OF INTERPHASE
- Cells with highly active metabolism will proceed with S stage (irreversible).
DNA REPLICATION STAGE (S)
PROCEDURES DURING S STAGE
INITIATION
ELONGATION
TERMINATION
PROCEDURE DURING S STAGE
- Start the process of DNA replication.
INITIATION
PROCEDURE DURING S STAGE
- Sustain the process of DNA replication.
ELONGATION
PROCEDURES DURING S STAGE
- Stop the process of DNA replication.
TERMINATION
STAGES OF INTERPHASE
- Initiation of development of centrioles (for production of spindle fibers in cell division) and rapid synthesis of ribosomes (protein synthesis visible through the nucleolus) in preparation for cell division.
FINAL GROWTH (G2) STAGE
2 DIFFERENT PROCESS OF CELL DEVELOPMENT
MITOSIS
MEIOSIS
2 DIFFERENT PROCESS OF CELL DEVELOPMENT
- Cell division of somatic cells in the body.
MITOSIS
2 DIFFERENT PROCESS OF CELL DEVELOPMENT
- Cell division of sex cells in the body.
MEIOSIS
CELL CYCLE: CELL DIVISION
PROPHASE
METAPHASE
ANAPHASE
TELOPHASE
CELL CYCLE: CELL DIVISION
- Pairing of chromosomes in preparation for distribution to the daughter cells.
PROPHASE
CELL CYCLE: CELL DIVISION
- Exchange of materials between chromosomes to allow differences for parents and siblings.
METAPHASE
CELL CYCLE: CELL DIVISION
- Segregation of chromosomes to the new daughter cells.
ANAPHASE
CELL CYCLE: CELL DIVISION
- Division of cell membrane (completed daughter cells).
TELOPHASE
- It is responsible for the development of haploid cells in the human body.
REPRODUCTIVE SYSTEM
- It is associated with the preparation and development of offspring.
HAPLOID CELLS
TWO TYPES OF CELL IN HUMAN BODY
DIPLOID (2n)
HAPLOID (n)
TWO TYPES OF CELL IN HUMAN BODY
- A combination of maternal and fraternal DNA.
DIPLOID (2n)
TWO TYPES OF CELL IN HUMAN BODY
- Reduced cell DNA content (for combination).
HAPLOID (n)
Humans have _____________ for Diploid and _____________ for Haploid
46 CHROMOSOMES (diploid), 23 CHROMOSOMES (haploid)
- Can either be make sex cells (gametes)— sperm, and the female gametes—ovum (egg).
