Question

what is translation?
translation
once mrna has been transcribed in the nucleus, the job of deciphering the genetic message can begin. decoding the message carried by mrna into the proteins needed to carry out life processes is called translation. translation plays a major role in gene expression.

Explanation:

Translation, in the context of molecular biology (a subfield of Biology), is the process where after mRNA is transcribed from DNA in the nucleus, the mRNA's genetic message is decoded to synthesize proteins. These proteins are essential for carrying out life processes, and translation (RNA → Protein) is a key step in gene expression, as shown in the diagram with the flow from DNA to RNA (transcription) and then RNA to Protein (translation).

Answer:

Translation is the process where the genetic message carried by mRNA (after transcription from DNA in the nucleus) is decoded to synthesize proteins, which are needed for life processes, and it plays a major role in gene expression (involving the RNA → Protein step as part of the central dogma of molecular biology).
