“Given a DNA strand, return its RNA Complement Transcription.”
should be
“Given a DNA strand, return its RNA complement.”
There are two separate issues addressed by this edit.
First, complement transcription shouldn’t be capitalized since it’s not a proper noun. DNA and RNA are capitalized because they are abbreviations.
Second, the exercise instructions indicate we’re returning the RNA complement. Transcription is the process of copying DNA to RNA, not the product.
