Stylistic comment: Remove TODOs when you've implemented the code

elif nucleotide == 'C':
return 'G'
else:
return 'C'

Stylistic comment: Instead of using a bunch of if and else statements and now that you've learned what dictionaries are, you could do something like this as well :
nucleotide_complements' = {'A':'T', 'T':'C', 'C':'G', 'G':'C'}
return nucleotide_complements[nucleotide]

orf_list = orf_list + find_all_ORFs_oneframe(dna[1:])
#second offset frame
orf_list = orf_list + find_all_ORFs_oneframe(dna[2:])
return orf_list

If frames were larger than 3 codons long, you would have to copy the same line over and over, so putting it in a loop is a good choice.

if len(orf) > longest_length:
longest_orf = orf
longest_length = len(orf)
return longest_orf

Technically longest_org = orf is redundant

I made a few stylistic suggestions for future reference. Keep up the good work!
