Step 1: What is Genetic Code?
The genetic code is a set of rules that dictates how sequences of nucleotides in DNA and RNA are translated into amino acids, which make up proteins.
Step 2: Characteristics of Genetic Code.
1. Universal: The genetic code is the same in almost all organisms.
2. Degenerate: Multiple codons can code for the same amino acid.
3. Unambiguous: Each codon specifies only one amino acid.
4. Non-overlapping: Codons are read in a sequence without overlap.
5. Commaless: The genetic code does not contain punctuation marks between codons.
6. Start and Stop Signals: There are specific codons (AUG for start, UAA, UAG, UGA for stop) that signal the beginning and end of protein synthesis.
Step 3: Conclusion.
Thus, the genetic code is a key feature of life, enabling the accurate translation of genetic information into functional proteins.
Final Answer:
\[
\boxed{\text{The genetic code is universal, degenerate, unambiguous, non-overlapping, and contains start and stop codons.}}
\]
