Final answer:

DNA replication occurs in reverse direction from the template strand. Transcription involves RNA synthesis in the 5' to 3' direction, which can be considered as happening in reverse. Translation involves reading the mRNA in the 5' to 3' direction to form a protein.

Step-by-step explanation:

During DNA replication, the synthesis of the new DNA strand can only happen in the 5' to 3' direction. This means that the replication of the second strand occurs in the reverse direction from the template strand.

In transcription, the process of synthesizing RNA from a DNA template, the RNA polymerase enzyme reads the template DNA in the 3' to 5' direction and creates the complementary RNA strand in the 5' to 3' direction. So, in a way, transcription is also happening in the reverse direction.

In translation, which is the process of protein synthesis, the ribosomes read the mRNA in the 5' to 3' direction and assemble the amino acids in the correct sequence to form a protein.
