Step 1

During transcription, the DNA sequence of a gene is copied into messenger RNA (mRNA). This process occurs in the nucleus of the cell, where the enzyme RNA polymerase binds to the promoter region of the gene and synthesizes a complementary RNA strand based on the Show more…

Key Concepts

Transcription

Transcription is the process by which the genetic information encoded in a DNA strand is copied into a complementary strand of RNA. This step is essential for gene expression as it transforms the static DNA code into a dynamic RNA message that can be used within the cell.

Translation

Translation is the subsequent process in which the RNA message produced during transcription is decoded to assemble proteins. In this process, ribosomes and transfer RNA (tRNA) work together to interpret the RNA sequence and synthesize a corresponding chain of amino acids, ultimately folding into a functional protein.
