WebThis strand cannot be made continuously as DNA polymerase can only build the new strand in opposite direction. Thus, DNA polymerase will need to keep detaching and reattaching to this strand, and this results in the new strand being built in short segments. This strand is called the lagging strand.

This process is called gene expression and involves two phases, transcription and translation. Transcription is the process by which a transcript of the gene is made in the form of mRNA. It serves as the working copy of the gene.

WebThere are three main types of RNA participate in protein synthesis, these are: 1.
