Chapter 6b:Eukaryotic Chromosomes, part 1: ANATOMY

Learning Objectives:

1. To know the three main types of repetitive DNA sequences found in eukaryotic genomes, their general location on the chromosome, and their frequency of occurance.  (see page 239 for the list).
 

2. To know the significance of transposable elements, in terms of middle-repetitive sequences. (pages 241-246)

3. To be able to describe the type of DNA associated with centromeres (alpha satellite DNA - it is curved!) and where (and how) the microtubules are attached.

4. To know the type of DNA sequences found in Telomeres, what type of structures are unique to these motifs, and the significance of this, in terms of cancer and the aging process.
