What do translation and transcription work together to make apex?

Transcription and translation are part of the gene expression process (information from DNA is used for protein synthesis).
Transcription is the first step in gene expression which involves copying a DNA sequence to make an RNA molecule-messenger RNA (mRNA). The main enzyme for transcription is RNA polymerases, which binds nucleotides to form an RNA strand, using a DNA strand as a template.
Translation is a process of "decoding" the mRNA in order to synthesize a protein (polypeptide). In a mRNA, the instructions for building a polypeptide are RNA nucleotides read in groups of three-codons. Codons are specified for different amino-acids (but it is possible that one amino-acid corresponds to two or three codons). Amino-acids are structural units for synthesis of the polypeptide chain.
