Restriction map of a plasmid

Here's more practice for you to use to create a restriction map.  Dr. Bird did another post on this type of exercise.

You can assume the plasmid is circular.  Note that there is more than one solution to this exercise!

 

... and here's the way to find the solutions!

Chromosome inversions and Meiosis

Here's a typical problem involving a chromosome inversion.  Your task is to find out what the end products of meiosis (i.e. haploid cells) will be after a specific crossover during prophase I.

Here's how I solve this:

Restriction Mapping example

Dr. Bird goes over this restriction mapping example.  Here are the data:

Create a circular restriction map from this.

The answer key is here:

 

You can make it larger by clicking on the YouTube logo in the bottom-right corner and making it full screen from the YouTube site.
