**Core Concept**
The genetic code is a set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences) into proteins. It is **nearly universal**, with most organisms using the same code. The code is based on the sequence of **nucleotides** in DNA or RNA.

**Why the Correct Answer is Right**
Since the actual options are not provided, let's discuss the general features of genetic coding: it is **complementary**, **degenerate**, **non-overlapping**, and **universal**. The correct answer would be an option that does not fit one of these characteristics.

**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it stated a true feature of genetic coding, such as being **degenerate**.
**Option B:** Might be wrong if it mentioned the code being **non-overlapping**, which is a true feature.
**Option C:** Could be incorrect if it described the code as **universal**, which is largely true.
**Option D:** Without the actual options, let's assume it represents a false feature, such as the genetic code being **ambiguously overlapped**.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the genetic code is **degenerate**, meaning more than one codon can code for the same amino acid. This is important for understanding genetic mutations and their effects on protein synthesis.

**Correct Answer:** Correct Answer: D.
