A Java small class to find all the genes from a DNA string stored in a plain text file. The library edu.duke is a dependency for the class to work, it should be added into the Java IDE to compile with no errors. Download link http://www.dukelearntoprogram.com/downloads/archives/courserajava.jar

Okay here are my answers
For Final Assignment Week 2
(NOTE: not the answer for practice quiz !!! )

TOTAL GENES = 69
Total number of strings with length greater than 60 : 23
Total number of strings with CG Ratio greater than 0.35 : 40
Longest gene length is : 489
Total number of occurances of CTG is : 224
Question 1 : turkey ,duck and quails
Question 2 :The method mystery is given a string and it returns a string which is the same string but with the first three T's removed.
Hope this clears the doubts !!!!...

Warning : Copying other's answer wont pay off your money and time efforts !!

GOOD LUCK!!!!

Wrong answer

it is the correct answer it worked with me i passed it with 90%

yes this is the correct answer , worked for me and passed with 100% can u please share your code ? @citoyenu
