DNA replication occurs in the nucleus. DNA transcription occurs in the nucleus. mRNA translation occurs at ribosomes.


DNA replication occurs in the S-phase in interphase when the cell gets signal to start preparing for division. Here. the DNA will divide semi-conservatively.

DNA transcription and DNA translation are part of protein synthesis. DNA transcription occurs by copying a length of DNA template (gene coding for a polypeptide) to form mRNA (messenger RNA).

DNA translation occurs when mRNA sequence is converted into complementary amino acid sequence with help of tRNA (transfer RNA) molecules and enzymes like peptidyl transferase at the ribosomes.
