Please consider the features of Java classes, and then define a Java class for a DNA sequence object to include instance variable names and methods that you can use to define a piece of DNA sequence. You can use a UML (Universal Modeling Language) diagram to define your class (see an example in Deitel & Deitel page 87, the GradeBook class), or you can simply list the variable, and method's names, data type, and parameters the methods will take in.
