Creat an Eclipse Java project in your student folder named
HW1_DNA and create
a class named Main.
Add a function to our DNA program we developed in class that computes the
molecular weight of a strand of DNA. The molecular weight of Adenine is
135.128 grams/mol, Cytosine is 111.103 grams/mol, Guanine
is 151.128 grams/mol, and Thymine is 125.107 grams/mol.
/**
* Compute the molecular weight of a strand of DNA.
* @param dna: A string of ACGT in any case and no other characters.
* @return The molcular weight of the strand.
*/
public static double weight(String dna) {
...
}
-
Write a function that returns the character code of the nucleotide
that occurs most frequently. Use the function template below:
/**
* Compute which nucleotide occurs most frequently in a DNA strand.
* @param dna: A string of ACGT in any case and no other characters.
* @return The character code of the nucleotide that occurs the most..
*/
public static char max(String dna) {
...
}
-
Write a function that reverses a DNA strand.
/**
* Reverse a DNA strand.
* @param dna: A string of ACGT in any case and no other characters.
* @return The reverse of the dna parameter.
*/
public static String reverse(String dna) {
...
}
-
Its often important to compute the reverse complement
of a strand of DNA.
Write a function to do this (hint, its trivial given that we already
have functions for reverse and complement).
/**
* Compute the reverse complement of a DNA strand.
* @param dna: A string of ACGT in any case and no other characters.
* @return The reverse complement of dna.
*/
public static String reverseComplement(String dna) {
...
}
- Have your program print the molecular weight of the
H1N1 DNA strand in the
H1N1.fasta file as well
as print the nucleotide that occurs most frequently.

Make sure your program is on the
T: drive by the start of class Tuesday
September 8 in a folder named HW1_DNA. Also turn in a printout. Make
sure there are no bad line breaks in the printout and that methods are commented.
