dna2rna

Convert DNA sequence to RNA sequence

Syntax

SeqRNA = dna2rna(SeqDNA)

Description

SeqRNA = dna2rna(SeqDNA) converts a DNA sequence to an RNA sequence by replacing thymine (T) nucleotides with uracil (U) nucleotides.

Input Arguments

SeqDNA — DNA sequence

character vector | string scalar | row vector of integers | structure

DNA sequence, specified as one of the following.

• Character vector or string scalar consisting of the characters A, C, G, and T, and ambiguous characters R, Y, K, M, S, W, B, D, H, V, and N.

• Row vector of integers specifying a nucleotide sequence. For information on valid integers, see Mapping Nucleotide Integers to Letter Codes.

• Structure that contains a DNA sequence in the Sequence field. The fastaread, fastqread, emblread, getembl, genbankread, and getgenbank functions return structures with a Sequence field.

Example: SeqRNA = dna2rna("CGACTT") replaces the instances of T with U.

Data Types: double | char | string | struct

Output Arguments

SeqRNA — RNA sequence

character vector | row vector of integers

RNA sequence, returned as a character vector or a row vector of integers.

• If SeqDNA is a character vector or string scalar, then the function returns a character vector.

• If SeqDNA is a row vector of integers, then the function returns a row vector of integers.

• If SeqDNA is a structure, then the function returns a character vector or a row vector of integers depending on the data type of the Sequence field.
