2. GC ratio calculation
● DNA has four “letters” (“bases”): A, C, G, T
● GC ratio is the:
ratio of Gs and Cs, compared to As and Ts.
● Sequences are stored in ASCII text files, with
around 80 characters per line.
● Header lines in the file start with “>” and should
be skipped.
● Unknown bases are denoted with “N”.

3. DNA Fasta file example

4. GC ratio calculation in Python

6. GC ratio c alculation in Elixir

8. Elixir processes vs Go channels
● Elixir processes:
– “Named” mailboxes
– Mailbox and process tied together
● Go channels
– “Anonymous”, no name
– Channels are separate from go routines (can be
sent around, sent to functions etc).
● More?
