What is fragmentation?

Process in which a piece of body fragment of the parent organism develops into a mature individual

What is an example of fragmentation?

What is the growth phase known as?

interphase

What phase does a cell spend most of it's life?

interphase

What are 3 things that happen in interphase?

1.cells grow
2.nucleus makes a copy od DNA
3.Organelles are replicated

What are the 2 types of the division phase?

Mitosis and cytokinesis

What are 2-4 things that happen in prophase?

1.DNA condenses into chromosome
2.Centroles move to opposite ends of cell
3.spindle fibres form from the cetroles
4. Nuclear membrane dissolves

What are 2 things that happen in metaphase?

1.spindle fibers attach to centromeres
2. chromosomes align along the equatorial plate.

What are 2 things that happen in anaphase?

1.Spindle fibers shorten
2.Centromere splits and pulls chromatids to opposite ends of the cell

What are the 3 things that happen in telophase?

1. Chromosomes relax into chromatin
2.Nuclear membrane reappears
3.spindle fibers disappear

is cytokinesis a part of mitosis?

no

What happens during cytokinesis?

Cytoplasm divides by forming cleavage furrows for animal cells, and cell plates for plant cells

How did Dr.Wilmut create dolly the clone?

1.removed nucleus from the egg cell
2.fused the adult body cell with egg cell
3.implanted fused cells into 3rd sheeps uterus

What is an issue with cloning?

do not live as long

What are some positive implications of cloning (2)

1. mass production
2.Reproduction of endangered species
