Question

If two people want to use symmetric encryption to conduct a confidential conversation, how many keys do they need?

a) One
b) Two
c) Three
d) Four

Answer 1

To conduct a confidential conversation using symmetric encryption, two people only need one key. For RNA translation, three sequential RNA nucleotides, a codon, provide the code for a single amino acid.

Step-by-step explanation:

If two people want to use symmetric encryption to conduct a confidential conversation, they only need one key.

This is because symmetric encryption is a type of encryption where the same key is used to both encrypt and decrypt the messages. Both parties must have a copy of this secure key and keep it private from anyone else to maintain confidentiality.

In the context of RNA translation into proteins, it takes three sequential RNA nucleotides, or 'letters', to code for a single amino acid. This sequence of three nucleotides is known as a codon.

The use of three-letter codons in RNA ensures that the genetic code can specify all 20 common amino acids used to build proteins.
