Translating DNA to amino acids

Translating DNA to amino acids#

Write a function translate that takes a list of DNA bases and yields a list of amino acids. If there are any bases left over at the end, you should raise an exception (your choice). You should also raise an exception if the string contains something other than DNA bases.

For example:

>>> translate(list("ATGATCTCGTAA"))
['M', 'I', 'S', '_']
>>> translate([])

Write tests (using doctest or unittest or assert) to check your work. (We won’t be ‘marking’ it—convince yourself you got it right!)
