Write a python function called substrand() that takes two DNA strands (strings) as parameters and checks if one is a subst ring of the other. Your program should do the following: 1. take two strings as parameters. The function will check if the second is a substring of the first. 2. Check if the sub DNA strand is a substring of the first DNA strand. 3. print a message indicating whet her it is or not. If it is a substring, then also print the position of the first letter. Example: substrand(“AATTCAT”, “CAT”) prints: CAT is a substrand of AATTCAT starting at position 4 substrand(“CAAAT”, “CAT”) prints: CAT is not a substrand of CAAAT Hint: use the string.find() method.

Question
Write a python function called substrand() that takes two DNA strands (strings) as parameters and checks if one is a subst
ring of the other. Your program should do the following:
1. take two strings as parameters. The function will check if the second is a substring of the first.
2. Check if the sub DNA strand is a substring of the first DNA strand.
3. print a message indicating whet
her it is or not. If it is a substring, then also print the
position of the first letter.
Example:
substrand(“AATTCAT”, “CAT”)
prints:
CAT is a substrand of AATTCAT starting at position 4 substrand(“CAAAT”, “CAT”)
prints:
CAT is not a substrand of CAAAT
Hint: use the string.find() method.
