if we say codon for DNA what we say for mRNA, tRNA and rRNA

Answer 1

For mRNA (messenger RNA), we refer to it as a nucleotide sequence or mRNA sequence.

For tRNA (transfer RNA), we refer to it as an anticodon or a tRNA molecule.

For rRNA (ribosomal RNA), we typically refer to it as a ribosome or a ribosomal subunit.
