# Bio::Sequence::NA

# DESCRIPTION

Bio::Sequence::NA represents a bare Nucleic Acid sequence in bioruby.

# USAGE

    # Create a Nucleic Acid sequence.
    dna = Bio::Sequence.auto('atgcatgcATGCATGCAAAA')
    rna = Bio::Sequence.auto('augcaugcaugcaugcaaaa')

    # What are the names of all the bases?
    puts dna.names
    puts rna.names

    # What is the GC percentage?
    puts dna.gc_percent
    puts rna.gc_percent

    # What is the molecular weight?
    puts dna.molecular_weight
    puts rna.molecular_weight

    # What is the reverse complement?
    puts dna.reverse_complement
    puts dna.complement

    # Is this sequence DNA or RNA?
    puts dna.rna?

    # Translate my sequence (see method docs for many options)
    puts dna.translate
    puts rna.translate

### Public Class Methods

new(str) click to toggle source

Generate an nucleic acid sequence object from a string.

    s = Bio::Sequence::NA.new("aagcttggaccgttgaagt")

or maybe (if you have an nucleic acid sequence in a file)

    s = Bio::Sequence:NA.new(File.open('dna.txt').read)

Nucleic Acid sequences are always all lowercase in bioruby

    s = Bio::Sequence::NA.new("AAGcTtGG")
    puts s                                  #=> "aagcttgg"

Whitespace is stripped from the sequence

    seq = Bio::Sequence::NA.new("atg\nggg\ttt\r  gc")
    puts s                                  #=> "atggggttgc"

Arguments:

- (required) str: String

Returns | Bio::Sequence::NA object

    # File lib/bio/sequence/na.rb, line 75
    def initialize(str)
      super
      self.downcase!
      self.tr!(" \t\n\r",'')
    end

randomize(*arg, &block) click to toggle source

Generate a new random sequence with the given frequency of bases. The sequence length is determined by their cumulative sum. (See also Bio::Sequence::Common#randomize which creates a new randomized sequence object using the base composition of an existing sequence instance).

    counts = {'a'=>1,'c'=>2,'g'=>3,'t'=>4}
    puts Bio::Sequence::NA.randomize(counts)  #=> "ggcttgttac" (for example)

You may also feed the output of randomize into a block

    actual_counts = {'a'=>0, 'c'=>0, 'g'=>0, 't'=>0}
    Bio::Sequence::NA.randomize(counts) {|x| actual_counts[x] += 1}
    actual_counts                     #=> {"a"=>1, "c"=>2, "g"=>3, "t"=>4}

Arguments:

- (optional) hash: Hash object

Returns | Bio::Sequence::NA object

    # File lib/bio/sequence/compat.rb, line 82
    def self.randomize(*arg, &block)
      self.new('').randomize(*arg, &block)
    end

### Public Instance Methods

at_content() click to toggle source

Calculate the ratio of AT / ATGC bases. U is regarded as T.

    s = Bio::Sequence::NA.new('atggcgtga')
    puts s.at_content                       #=> 0.444444444444444

Returns | Float

    # File lib/bio/sequence/na.rb, line 317

at_skew() click to toggle source

Calculate the ratio of (A - T) / (A + T) bases. U is regarded as T.

codon_usage() click to toggle source

Returns counts of each codon in the sequence in a hash.

    puts s.codon_usage                #=> {"gcg"=>1, "tga"=>1, "atg"=>1}

This method does not validate codons! Any three letter group is a 'codon'. So,

    s = Bio::Sequence::NA.new('atggNNtga')
    puts s.codon_usage                #=> {"tga"=>1, "gnn"=>1, "atg"=>1}

Also, there is no option to work in any frame other than the first.

translate(frame = 1, table = 1, unknown = 'X') click to toggle source

Translate into an amino acid sequence.

    s = Bio::Sequence::NA.new('atggcgtga')
    puts s.translate                        #=> "MA*"

By default, translate starts in reading frame position 1, but you can start in either 2 or 3 as well,

    puts s.translate(2)                     #=> "WR"
    puts s.translate(3)                     #=> "GV"

You may also translate the reverse complement in one step by using frame values of -1, -2, and -3 (or 4, 5, and 6)

    puts s.translate(-1)                    #=> "SRH"
    puts s.translate(4)                     #=> "SRH"
    puts s.reverse_complement.translate(1)  #=> "SRH"

The default codon table in the translate function is the Standard Eukaryotic codon table. The translate function takes either a number or a Bio::CodonTable object for its table argument. The available tables are (NCBI):

    1. "Standard (Eukaryote)"
    2. "Vertebrate Mitochondrial"
    3. "Yeast Mitochondorial"
    4. "Mold, Protozoan, Coelenterate Mitochondrial and Mycoplasma/Spiroplasma"
    5. "Invertebrate Mitochondrial"
    6. "Ciliate Macronuclear and Dasycladacean"
    9. "Echinoderm Mitochondrial"
    10. "Euplotid Nuclear"
    11. "Bacteria"
    12. "Alternative Yeast Nuclear"
    13. "Ascidian Mitochondrial"
    14. "Flatworm Mitochondrial"
    15. "Blepharisma Macronuclear"
    16. "Chlorophycean Mitochondrial"
    21. "Trematode Mitochondrial"
    22. "Scenedesmus obliquus mitochondrial"
    23. "Thraustochytrium Mitochondrial"

If you are using anything other than the default table, you must specify frame in the translate method call,

    puts s.translate                #=> "MA*"  (using defaults)
    puts s.translate(1,1)           #=> "MA*"  (same as above, but explicit)
    puts s.translate(1,2)           #=> "MAW"  (different codon table)

and using a Bio::CodonTable instance in the translate method call,

    mt_table = Bio::CodonTable[2]
    puts s.translate(1, mt_table)           #=> "MAW"

By default, any invalid or unknown codons (as could happen if the sequence contains ambiguities) will be represented by 'X' in the translated sequence. You may change this to any character of your choice.

    s = Bio::Sequence::NA.new('atgcNNtga')
    puts s.translate                        #=> "MX*"
    puts s.translate(1,1,'9')               #=> "M9*"

The translate method considers gaps to be unknown characters and treats them as such (i.e. does not collapse sequences prior to translation), so

    s = Bio::Sequence::NA.new('atgc--tga')
    puts s.translate                        #=> "MX*"

Arguments:

- (optional) frame: one of 1,2,3,4,5,6,-1,-2,-3 (default 1)

- (optional) table: Fixnum in range 1,23 or Bio::CodonTable object (default 1)

- (optional) unknown: Character (default 'X')

Returns | Bio::Sequence::AA object

    # File lib/bio/sequence/na.rb, line 232
