Final answer:
It takes three nucleotides, or 'letters,' of an RNA molecule to code for a single amino acid. The sets of three nucleotides are called codons and are fundamental to the process of protein synthesis. The correct option is c) Three
Step-by-step explanation:
The answer to the question about the number of "letters" of an RNA molecule required to code for a single amino acid is C. 3. This is because the genetic code is read in triplets, where each triplet, known as a codon, corresponds to a specific amino acid. The process of translating RNA into proteins utilizes these codons in sets of three nucleotides to direct the incorporation of specific amino acids into the growing polypeptide chain.
In a writer and server program communicating via sockets, only one identical writer program is required.
In this scenario, the writer program sends data to the server program through sockets. The server then processes and responds to the data received.
The number of writer programs needed does not depend on the number of machines, as the communication happens between the writer and server through sockets.
The correct option is c) Three
