DNA TO RNA USING USER DEFINED FUNCTION

Question

[kareemmoussa]

Hello, While doing my assignment (DNA TO RNA USING USER DEFINED FUNCTION) i ran the following script

DNA <- "ACCTGTCATCATCCC"
DNA_to_RNA.R <- function(DNA){
    RNA <- gsub("T", "U", DNA)
    Basecheck <- substring(RNA, seq(1, nchar(RNA), by = 1))
    return(RNAsequence)
}

My question is can i replace gsub with user defined function that converts dna to rna Thanks

Is this the same assignment as here? script in R to convert DNA to RNA sequence

Also, why are you splitting the converted string by base? gsub already did the job. Still, the variable you are returning does not exist in your function. Why user-defined? gsub is already as lowlevel as it gets. Do not start with something like looping over every base, this is terribly inefficient.
