Mitosis Vs Meiosis

Question 1

What occurs in prophase?

Answer 1

Chromosomes condense = visible
Nuclear membrane disintegrates

Question 2

What occurs in metaphase?

Answer 2

Chromosomes attach to spindle fibres by centromere
Line up along the equator

Question 3

What occurs in anaphase?

Answer 3

Chromosomes are pulled apart to opposite poles of the cell
By centromeres splitting, spindles shorten

Question 4

What occurs in telophase?

Answer 4

Spindles disintegrate
Nuclear membrane reform
Chromosomes lengthen, not visible

Question 5

What is the significance of mitosis?

Answer 5

Genetically identical daughter cells, genetic stability
Repair/replacement
Growth and development

Question 6

Why are homologous chromosomes not identical?

Answer 6

Same genes at same loci however different alleles

Question 7

What is the significance of producing haploid eggs?

Answer 7

To produce genetic variation
Ensure the diploid number is restored in the zygote
