Proteins are key to structure & functions cells produce diverse proteins for structural, enzymatic, communication, transport, and defense roles. Each amino acid has its unique transfer rna for delivering them to the protein synthesis takes place in the ribosome of the messenger rna. Anticodon of transfer rna binds to triplet code through base pairing to. Lack of growth hormone binding to growth hormone receptor prevents cell cycle progression and mitosis. Metastasis is spread of primary tumor tumor begins with one mutated cell in forming a primary tumor due to unregulated cell growth.
