Evaluate each expression
The simple rules to follow are:
(1) All expressions in bracket will be evaluated based on its data type
(2) Divisions will return only integer values
(3) Integers immediately after string values will be concatenated (not added)
So, the results are as follows:
Evaluate till a string is encountered
Followed by "."
Then:
-- because expressions after string operations are concatenated.
So, we have:
Evaluate till a string is encountered
So, we have:
Evaluate till a string is encountered
So, we have:
Evaluate till a string is encountered
--- multiply 2 and 3, then concatenate
So, we have:
Since a string starts the expression, the whole expression will be concatenated except the multiplication and the expressions in bracket.
So, we have:
Answer:
Explanation:
The following code is written in Python. It continues looping and asking the user for an oligonucleotide sequence and as long as it is valid it outputs the reverse complement of the sequence. Otherwise it exits the loop
letters = {'A', 'C', 'G', 'T'}
reloop = True
while reloop:
sequence = input("Enter oligonucleotide sequence: ")
for x in sequence:
if x not in letters:
reloop = False;
break
if reloop == False:
break
newSequence = ""
for x in sequence:
if x == 'A':
newSequence += 'T'
elif x == 'T':
newSequence += 'A'
elif x == 'C':
newSequence += 'G'
elif x == 'G':
newSequence += 'C'
print("Reverse Complement: " + newSequence)
