Question

Write the Python Function program to find the RRi of Given Protein Sequence.

input: Two inputs will be one is Sequence and the other is Amino Acid.

Output: RRi

Example: Here input is a different sequence and Amino acid is "A".

This means for a given residue type, minimum RRI will be 1 and maximum will be total number of that type of residues in sequence. This value measures multiple runs of a residue in a sequence. RRI = Residue Repeat Information of ih amino acid RRI = IMEM E(R) N and R-Number of Repeats in occurrencej Examplel: In following sequence amino acid , occurs four times, RRI for A can be calculated using following equation: (1)2+(1)2+(1)2+(1)2+(12-10 GARAGRGARDEARTAG RRI(A) = 0 1+1+1+1+1 Example 2: In following sequence amino acid A occurs two times, first time two runs and second time three runs., RRI for A can be calculated using following equation GAARGRGAAARDERTG RRIA) = (2+3) = 2.6 Example 3: In following sequence amino acid A occurs once within five runs, RRI for A can be calculated using following equation GRGRGAAAAARDERTG RRICA) = (5)2 = 5

Code Example :

def Function(Sequence,AminoAcide):

# Your Code

Answer 1

#FUNCTION to calculate RRI

def calRRI(sequence,acid):
res=0
count=0
l = []
u=0
d=0
for x in sequence:
if(x == acid):
count+=1
elif(count>0):
l.append(count)
count=0
for x in l:
u+=(x**2)
d+=x
  
res = u/d
return res

seq = input("Enter Sequence: ")
acid = input("Enter acid character: ")
rri = calRRI(seq,acid)
print(rri)
