Understand that the central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein.
Identify that protein synthesis involves converting the genetic code into a functional protein, which occurs in two main steps.
The first step is transcription, where the DNA sequence of a gene is copied into messenger RNA (mRNA). This process takes place in the nucleus of eukaryotic cells.
The second step is translation, where the mRNA sequence is decoded by ribosomes to assemble amino acids into a polypeptide chain, forming a protein. This occurs in the cytoplasm.
Note that replication is the process of copying DNA, not directly involved in protein synthesis, and glycolysis and the citric acid cycle are metabolic pathways unrelated to the central dogma.
