Perhaps it would not be wrong to say that "translation/transcription goes in the direction of 3' to 5'" or "in the direction of 5' to 3'";that's because these statements are ambiguous, not specifying "XX's".
However, I am confused. So I would like to clarify by clarifying the "XX's".
Are the following understanding correct?
In the case of transcription, the RNA polymerase moves in the 3'→5' direction of the template strand of genome DNA, and the ribonucleotide attaches to the 3' side of the mRNA during synthesis, am I right?
In the case of translation, the ribosome moves (relatively) in the 5'→3' direction of the mRNA, and the amino acids are attached to the C-terminal side of the polypeptide, am I right?
The genetic code is "the sequence of the complementary strand of genomic DNA read in the 5'→3' direction, with T replaced by U". For example, if the sequence of the complementary strand of the genomic DNA is "5'-ATGTTT...termination codon-3'", the corresponding sequence of the mRNA is "5'-AUGUUU...termination codon-3'", which is "N-terminal - methionine - phenylalanine ...C-terminal" sequence.
