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 is decoded by ribosomes in the cytoplasm to assemble amino acids into a polypeptide chain, forming a protein.
Note that splicing is a modification step of mRNA, and replication is the process of copying DNA, both of which are distinct from the two main steps of protein synthesis.
