Module 6 Lab Quiz

DNA Fingerprinting & Cell Division

What occurs during prophase of mitosis? -

Chromatin condenses to chromosomes

What occurs during metaphase of mitosis? -

Chromosomes line up in the middle of the cell

What occurs during anaphase of mitosis? -

Chromosomes separate and move towards opposite poles of the cell

What occurs during telophase of mitosis? -

Nuclear membrane reforms

During meiosis I, homologous chromosomes: -

Separate into different cells

At the end of meiosis, one diploid parent cell produces: -

Four haploid daughter cells

In the pop bead model, homologous chromosomes were represented as: -

A matching pair of chromosomes carrying the same genes but possibly different alleles

Which statement best describes the difference between meiosis I and meiosis II? -

Meiosis I separates homologous chromosomes, while meiosis II separates sister chromatids.

Which statement correctly compares metaphase I and metaphase II? -

Homologous pairs line up in metaphase I, while individual chromosomes line up in metaphase II.

A student observes chromosomes lined up one by one at the cell's equator. This cell is most likely in: -

Metaphase II

Why is the orientation of homologous chromosome pairs during metaphase I important? -

It influences which combinations of maternal and paternal chromosomes end up in gametes.

A student observes three cells in metaphase. Cell A has homologous chromosome pairs lined up side by side. Cells B and C each have individual chromosomes aligned at the metaphase plate. Which identification is correct? -

A = Meiosis I, B = Mitosis, C = Meiosis II
