The video explains the process of mRNA processing and translation. It begins with the mRNA receiving a methylated cap and poly-A tail. Translation starts when the ribosome attaches to the mRNA. tRNA molecules bring amino acids to the ribosome, matching their anticodons with mRNA codons. This process continues, forming a protein chain until a stop codon signals termination. The video highlights the roles of mRNA, tRNA, and ribosomes in protein synthesis.
