Possible typo in the intro section 'How proteins are made?'

[studuffy-moia]

In the text there it writes:

For example, the codon TCA (or UGA if we describe it as an RNA sequence) codes for S, the amino acid Serine.

Should that be UCA for the RNA sequence?

(I wasn't sure since I'm a complete novice in this, so apologies if I'm wrong. Maybe it's UGA reading it in reverse after transcribing TCA or something like that...)

sorry, indeed a typo
