Describe the function of each of the following in protein synthesis:

1. rRNA
2. mRNA
3. tRNA

mRNA - messenger RNA - complementary to DNA, it is formed in the nucleus. Unlike DNA however, it can move outside the nucleus.
tRNA - transfer RNA - a unique structure, at one section there is an anticodon, a series of 3 bases which are complementary to the code embedded on the newly formed mRNA. Additionally, another section has an amino acid attached, this is essential for protein synthesis.
rRNA - ribosomal RNA - forms ribosomes. Ribosomes are essential for protein synthesis. The newly formed mRNA leaves the nucleus and attaches to a ribosome. Upon attachment, the ribosome mediates the formation of a primary structure protein. The tRNA binds to the mRNA forming a codon-anticodon complex, this allows bonds to form between adjoining amino acids (attached to tRNA), this complex moves through the ribosome, which detaches the newly formed amino acid strand - thus forming a primary structure protein.

Messenger RNA molecules, also known as transcripts , carry the coding sequences for protein synthesis ; ribosomal RNA molecules form the core of a cell's ribosomes and transfer RNA molecules transport amino acids to the ribosomes during protein synthesis.
What is protein translation?
Translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins following the process of transcription of DNA to RNA in the cell's nucleus . The entire process is referred to as gene expression .
An mRNA sequence is read during translation using the genetic code , which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins .
Messenger RNA molecules, also widely recognized as transcripts, transport protein coding sequences ; ribosomal RNA molecules create the core of a cell's ribosomes (the frameworks in which protein synthesis takes place).
This basically handover RNA molecules transport amino acids to the ribosomes all through protein synthesis .
Thus, this is the function of each RNA .

mRNA carries genetic information from DNA to the ribosomes, rRNA forms the structural components of ribosomes, and tRNA delivers specific amino acids for protein assembly. Together, they facilitate the process of translating genetic code into functional proteins. This collaborative effort is critical for cellular function and growth.
