rna2dna - Convert RNA sequence to DNA sequence

Syntax

SeqDNA = rna2dna(SeqRNA)

Arguments

SeqRNA

RNA sequence specified by any of the following:

Character string with the characters A, C, G, U, and ambiguous characters R, Y, K, M, S, W, B, D, H, V, N,
Row vector of integers from the table Mapping Nucleotide Integers to Letter Codes.
MATLAB structure containing a Sequence field that contains an RNA sequence, such as returned by fastaread, fastqread, emblread, getembl, genbankread, or getgenbank.

Description

SeqDNA = rna2dna(SeqRNA) converts an RNA sequence to a DNA sequence by converting any uracil nucleotides (U) in the RNA sequence to thymine nucleotides (T). The DNA sequence is returned in the same format as the RNA sequence. For example, if SeqRNA is a vector of integers, then so is SeqDNA.

Examples

Convert an RNA sequence to a DNA sequence.

rna2dna('ACGAUGAGUCAUGCUU')

ans =
ACGATGAGTCATGCTT
