An understanding of why (and in what ways) it is important to be able to design and implement Repetitive Structures would be helpful pre-knowledge for tomorrow's exercises.
To minimise the class time spent discussing these simple ideas (many of you will have met already) we urge you to find time this evening to have a look at the following very short video:
The video - Improving Algorithm Design
by the use of Repeat Structures (Loops)
Loops - A video
Also offered is a video outining the wonders of the FASTA and FASTQ File Formats. This would be handy fo a couple of the exercises also.
