The Cell Cycle
Interphase (G1, S, G2), Mitosis, Cytokinesis
The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase where protein and membrane in synthesised
DNA Synthesis, Chromosomes replicate in the nucleus
Preparing for Mitosis by synthesising materials (Proteins) for division
Mitosis (M phase)
Prophase, Metaphase, Anaphase, Telophase
Division of the cytoplasm during cell division into two daughter cells
Chromosomes become visable, nuclear envelop dissolves, spindle forms
Chromosomes line up in the middle of the cell
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
After the chromosome separates, the cell seals off, creating to separate cells
Also known as the restriction point, checks if there is enough resources for the cell to divide, The cell is large enough to divide, The DNA in the nucleus is not damaged
Checks that the cell has adequate resources, Checks if the DNA and Chromosomes have been replicated without mistakes or damage
Occurs near the end of METAPHASE, Also known as the spindle checkpoint, Determines if all of the spindle fibres have correctly attached to the sister chromatids and the Chromosomes are lined up in the middle
A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
Binary Fission Steps
1. DNA Replication
2. Chromosome Segregation (when the replicated chromosomes move to different ends of cell)
3. Separation (new plasma membrane growth, cytoplasm divide, and new cell walls form around the new cells)
Prokaryotic Cells, A reproductive process that involves only one parent and produces offspring that are identical to the parent.
A form of asexual reproduction of yeast in which a new cell grows out of the body of a parent.
A form of asexual reproduction in which plants produce genetically identical offshoots (clones) of themselves, which then develop into independent plants.
An asexual reproductive process in which an organism forms a special cell called a spore.
A means of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals.
Asexual reproduction in which females produce offspring from unfertilised eggs.
Advantages of Asexual Reproduction
Faster reproduction, only need 1 individual to recreate cells
Disadvantages of Asexual Reproduction
Very little genetic variation among offspring
Hydrogen Bonds (DNA)
Bonds that form between the nitrogenous bases that form the "rungs" of the DNA ladder
A phosphate group is just a phosphorus atom bound to four oxygen atoms
5' and 3' ends of DNA
The 5' and 3' mean "five prime" and "three prime", which indicate the carbon numbers in the DNA's sugar backbone. The 5' carbon has a phosphate group attached to it and the 3' carbon a hydroxyl group. This asymmetry gives a DNA strand a "direction".
Mitosis in Plant Cells
Has no Centrioles, Aster, or Furrow, Has a cell plate which forms a cell wall
Mitosis in Animal Cells
Has centrioles and is circular, No cell plate
A process of programmed cell death that occurs in multicellular organisms when the cell is damaged or has a deformity
Threadlike structures made of DNA molecules that contain the genes
Two identical chromosomes that split and contain the same genetic material
Region of a chromosome where the two sister chromatids attach
