1. mRNA carries the genetic code: mRNA is transcribed from DNA in the nucleus and carries the genetic code for a specific protein to the ribosomes in the cytoplasm.
2. Ribosomes are the protein synthesis machines: Ribosomes are complex structures made of rRNA (ribosomal RNA) and proteins. They act as the "reading machines" for mRNA, decoding the genetic information.
3. tRNA brings the building blocks: tRNA molecules are responsible for bringing the correct amino acids (the building blocks of proteins) to the ribosome, based on the codons in the mRNA. Each tRNA molecule has an anticodon that matches a specific codon on the mRNA.
4. Amino acids are linked together: As the ribosome moves along the mRNA, it reads each codon. For each codon, the corresponding tRNA brings its amino acid. The ribosome then links the amino acids together in a chain, forming the polypeptide chain that will eventually become a functional protein.
In summary, mRNA, ribosomes, and tRNA work together in a complex process called translation to synthesize proteins from the genetic code.
