To do this, the DNA is “read” or transcribed into an mRNA molecule. The mRNA then provides the code to form a protein by a process called translation. Through the processes of transcription and translation, a protein is built with a specific sequence of amino acids that was originally encoded in the DNA.

The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

It highlights their role in RNA processing, particularly in tRNA, rRNA, and mRNA, often through self-splicing. Key examples include ribonuclease P and Group I and II introns. Additionally, it touches on spliceosomes and viroids, noting that viroids can infect plants and exhibit self-splicing capabilities similar to ribozymes.

RNA interference (RNAi) involves small interfering RNAs (siRNAs) and microRNAs (miRNAs) that can suppress gene expression and combat viruses.

The segmentation is controlled by maternal mRNA gradients, particularly bicoid and nanos, influencing genes like hunchback and even-skipped. These gradients function as transcription factors, facilitating gene activation patterns crucial for segment formation.

It describes the roles of various RNA types, including mRNA for polypeptides and non-coding RNAs for regulation. Different RNA polymerases perform transcription, while pre-mRNA processing converts it into mature mRNA through intron removal and addition of a 5' cap and poly(A) tail.
