A few impressions and thoughts

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”.

GC ratio c alculation in Elixir
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?
