Activity 3

Mitosis and Asexual Reproduction


Read the introduction

Read the Introduction

  • Asexual reproduction takes only one parent to produce offspring.

  • Mitosis occurs when a single cell divides to produce two identical daughter cells.


Activity 3

Challenge

  • If a genetically modified cell undergoes mitosis, how likely is it that the daughter cells will contain the inserted gene?


As you watch the simulation i n each phase of mitosis note the chromosomes

As you watch the simulation, in each phase of mitosis note the chromosomesÔÇÖ:

  • shape

  • position within the cell

  • movement within the cell


Modeling one pair of duplicated chromosomes

Modeling one pair of duplicated chromosomes


Activity 3

What is the probability that a daughter cell will receive an inserted gene from a genetically modified parent cell that undergoes mitosis?

  • In your discussion include:

    • chromosomes

    • parent cell

    • daughter cell

    • gene


Analysis 3

Analysis 3

  • A friend of yours claims that every genetically modified single-celled organism that reproduces asexually would pass along the inserted gene to its daughter cells. Based on your work in this activity, is that claim valid? Explain.


Activity 3

Revisit the Challenge

  • If a genetically modified cell undergoes mitosis, how likely is it that the daughter cells will contain the inserted gene?
