Incorrect: The directions for making a protein are carried by DNA, not amino acids. Amino acids are the building blocks of proteins, but they do not carry the instructions for protein synthesis.
To make a protein, the process involves several steps:
1. The genetic information for making a protein is encoded in the DNA molecules of the cell.
2. The DNA sequence containing the instructions for a specific protein is first transcribed into messenger RNA (mRNA) in a process called transcription.
3. The mRNA molecule then carries the genetic code from the nucleus to the ribosomes in the cytoplasm of the cell.
4. At the ribosomes, the process of translation occurs, where the mRNA is read to produce a chain of amino acids, which are the building blocks of proteins.
5. Transfer RNA (tRNA) molecules bring specific amino acids to the ribosomes, based on the codons (three-letter sequences) on the mRNA.
6. The growing chain of amino acids, called a polypeptide, folds and eventually forms a functional protein.
In summary, the directions for making a protein are carried by DNA, transcribed into mRNA, translated into a chain of amino acids by ribosomes, and eventually form a functional protein.
