Biology Cell Division Advanced Teaching & Coaching 2023.What is cell division - ANSWER The process by which a cell divides to create daughter cells. What are the two possible products of cell division? (What kinds of cells are generated) - ANSWER The process can produce either genetically unique cells, or genetically identical cells. What is the purpose of creating genetically unique cells? - ANSWER •So that offspring have a better chance of survival. •Variation increases the chances of survival. What is the purpose of creating genetically identical cells? - ANSWER In the event that a cell is damaged or dies, a new cell may take its place. When a parental cell undergoes cell division, what are the resulting cells called? - ANSWER Daughter Cells What does asexual reproduction imply/mean? Hint: (____ Organism) - ANSWER It implies a new organism. Offspring will be exact genetic copies of the parent. What does a bacterial chromosome consist of? - ANSWER A circular piece of DNA, that is many times larger than the cell. It is compressed. This is wrapped around a histone protein. When does the process of Binary Fission begin? In other words, what event signifies the beginning of this process? - ANSWER It starts when the DNA of the bacterial chromosome begins to replicate at a specific location. What is the specific location that Binary Fission starts? - ANSWER The Origin of Replication What occurs in Binary Fission? (The basic events) - ANSWER • Starts when the DNA of the bacterial chromosome begins to replicate at a specific location called the origin of replication. • The two copies of the DNA move apart to opposite ends of the cell • While the DNA is being replicated the cell grows in size. • When DNA replication is finished the cell membrane grows inward and the new cell wall is formed. • Two daughter cells are formed. What are some characteristics of Eukaryotic Chromosomes? - ANSWER •A Eukaryotic cell may have multiple chromosomes. •Every species has a specific characteristic number. •They have a linear shape. What are some characteristics of Prokaryotic Chromosomes? - ANSWER •A Prokaryotic cell only has one chromosome. •It is circular. What must a cell do before it can divide? - ANSWER It must first replicate its DNA. What is a cell required to do when it undergoes cell division, in terms of the number of chromosomes? - ANSWER The number of chromosomes must be the same.
