The given diagram illustrates the unidirectional flow of genetic information within a eukaryotic cell, a principle originally proposed by Francis Crick. Based on the cellular locations and structures shown, identify the processes labeled 'X' and 'Y', and the newly synthesized macromolecule 'Z'.

Step-by-step solution

Based on the provided diagram of the central dogma of molecular biology in a eukaryotic cell: 1. Process 'X' occurs in the nucleus where double-stranded DNA is used as a template to synthesize single-stranded mRNA. This process is called transcription. 2. Process 'Y' takes place in the cytoplasm at the ribosome (composed of large and small subunits). Here, the mRNA sequence is decoded to synthesize a protein. This process is known as translation. 3. Macromolecule 'Z' is the growing chain of amino acids being produc
