`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.
