1. Sequence complexity

Complexity (X) of a DNA fraction is the length of the longest nonrepeating sequence that could be produced by splicing together fragments in that fraction. What is the complexity of the highly-repetitive fraction in calf DNA? (You can estimate from Fig. 7.25b, C0t½ for the highly-repetitive fraction is ~ 4 x10-3, and this fraction represents about 15% of the genome.)

2. Measuring repeat number for a genome fraction

a) Given the following definitions derive an expression for R i where b) If the calf genome (N) is 10  9 bp, how many times is the repetitive fraction from a) repeated in the genome?
