The process that directs the manufacture of a cell product from a gene is called

gene expression

Explanation:

Gene expression is the process that allows proteins to be obtained from genes. Genes are sequences of DNA nucleotides that encode the information necessary for protein synthesis. This synthesis takes place in two steps: transcription and translation. Transcription takes place in the nucleus and in it one of the two strands that make up the double strand of DNA serves as a template for a specific sequence to be copied to a single stranded RNA molecule. Subsequently, this RNA goes out of the nucleus and carries the message - the nucleotide sequence - to the ribosomes, hence the name messenger RNA (mRNA). Translation is a cytoplasmic process in which the mRNA molecule is decoded to generate a specific chain of amino acids, called a polypeptide (the protein). The correspondence between nucleotides (mRNA) and amino acids (protein) is what is called the genetic code.
