Functions

func DNASequence

func DNASequence(length int, seed int64) (string, error)

DNASequence returns a random DNA sequence string of a given length and seed.

Example

// RandomDNASequence builds a DNA Sequence by only passing through arguments a length and a seed that will be use to generate a randomly the sequence. The length needs to be greater than two because every sequence already have a start and stop codon. Seed makes this test deterministic.
randomDNA, _ := DNASequence(15, 2)
fmt.Println(randomDNA)

Output:

TTAAATTAGATGCAA

func ProteinSequence

func ProteinSequence(length int, seed int64) (string, error)

ProteinSequence returns a random protein sequence string of a given length and seed. All returned sequences start M (Methionine) and end with * (stop codon).

Example

// RandomProteinSequence builds a Protein Sequence by only passing through arguments a length and a seed that will be use to generate a randomly the sequence. The length needs to be greater than two because every sequence already have a start and stop codon. Seed makes this test deterministic.
randomProtein, _ := ProteinSequence(15, 2)
fmt.Println(randomProtein)

Output:

MHHPAFRMFNTMYG*

func RNASequence

func RNASequence(length int, seed int64) (string, error)

RNASequence returns a random DNA sequence string of a given length and seed.
