Arrangement of three successive bases in the genetic code codes for `:`

Options

A. Protein
B. Nucleic acid
C. Plasmids
D. Amino acids

Answer

### Step-by-Step Solution:

1. **Understanding the Genetic Code**: The genetic code is a set of rules that defines how the information encoded in genetic material (DNA or mRNA) is translated into proteins. It is based on sequences of nucleotides.

2. **Structure of DNA and RNA**: DNA is a double-stranded molecule composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base. RNA, specifically mRNA (messenger RNA), is synthesized from one of the DNA strands during transcription.

3. **Codons**: In the mRNA, the genetic code is read in groups of three nucleotides, known as codons. Each codon corresponds to a specific amino acid or a stop signal during protein synthesis.

4. **Translation Process**: During translation, the mRNA is read by ribosomes, and transfer RNA (tRNA) molecules bring the appropriate amino acids to the ribosome based on the codon sequence. Each tRNA has an anticodon that is complementary to the mRNA codon.

5. **Amino Acids**: The arrangement of three successive bases (codons) in the mRNA codes for specific amino acids. This is fundamental to the synthesis of proteins, as amino acids are the building blocks of proteins.

6. **Conclusion**: Therefore, the arrangement of three successive bases in the genetic code codes for amino acids.

### Final Answer:
The arrangement of three successive bases in the genetic code codes for **amino acids**.
