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.

Sanger Sequencing

My first post in this section will be lazy:  here's a video.  It's good, though!  It's from http://www.dnai.org which is located in Cold Spring Harbor, New York.  They have wonderful lab facilities and are world-leaders in DNA education.
