Answer 1

many cell divisions required to generate new organism from fertilized egg

Question 2

What are certain features of cell division?

Answer 2

prokaryotes: faithfully replicate

Yeast: replicated DNA must be accurately distributed to daughter cells

Animal: most duplicate their macromolecules and organelles and double in size before they divide

Question 3

Meiosis vs Mitosis

Answer 3

Mitosis: - division of genetic material that produces daughter cells genetically identical
- accompanied by cytokinesis(division of cytoplasm into 2 cells
-asexual reproduction

Meiosis: -division of genetic material to produce daughter cells with half the hereditary material in the parent cell
-production of gametes
- sexual reproduction
