Follow-up Question

this code only prints random dna letters where is the game there are the questions below

Find the complement of a DNA strand: recall that a DNA strand is a combination of four
uppercase letters; A, T, C, and G. The letters A and T are complements, and the letters C
and G are complements. To find the complement of a DNA strand you must replace each
character with its complement. For example, ATCGG is the complement of TAGCC and
CCC is the complement of GGG. Your program must show a DNA of a predefined length
to the player and ask for its complement.
2. Find the reversed DNA strand: the order of the characters in a DNA strand should be
reversed. Examples: GCTAA is the reverse of AATCG and AA is the reverse of AA. Your
program must show a DNA of a predefined length to the player and ask for the reversed
strand.
3. Find the compressed DNA strand: all repeated characters in a DNA strand should be
replaced by the number of repeats followed by that character once. For example, 2C3AT
is the compressed form of CCAAAT, G2TA3GC is the compressed form of GTTAGGGC, and

Assignment # 2 Due: Oct 17th, 11:59 PM

TAGC is the compressed form of TAGC. Your program must show a DNA of a predefined
length to the player and ask for its compressed form.
4. Find the expanded DNA strand: this is the opposite of the compression technique
described in 3. So, it basically undoes the compressing. For example, CAGGTTT is the
expanded form of CA2G3T, TATTGC is the expanded form of TA2TGC, and TAGC is the
expanded form of TAGC. Your program must show a compressed DNA to the player and
ask for its expanded form. The expanded DNA must have the predefined length (n).

i was started but got only this far

import string

import random

from random import choice

print("Welcome to the DNA quiz game!")

u=input("Enter your username: ")

count=int(input("Hi " + u + ", please enter a positive integer for the DNA length: "))

print()

from random import choice

def String(length):

DNA=""

for count in range(length):

DNA+=choice("CGTA")

return DNA

print("Select an option [1-4] to answer a question or 5 to quit the game.")

print( "Win the game by scoring at least 10 points! ")

print(" 1. Complement [2 points] 2. Reverse [2 points] 3. Compress [3 point] 4. Expand [3 points] 5. Quit")

y=int(input())

while y==5:

break

while 1<=y<=4:

if y==1:

pass

while y<1 or y>5:

y=int(input("Please enter a digit between [1-5]: "))
