To identify the basic unit of the genetic code from the given options, we need to analyze each term in relation to genetics.

1. Transcription Unit: This refers to a segment of DNA that is transcribed into RNA. While important, it is not the basic unit of the genetic code itself.

2. Exon: This is a part of a gene that codes for proteins, but it is not the basic unit of the genetic code.

3. Intron: These are non-coding sequences present in genes and are spliced out during RNA processing. They do not represent the genetic code unit.

4. Anticodon: This is part of tRNA that pairs with the codon during translation, but it isn’t the basic unit of the genetic code.

5. Reading Frame: This is a way of dividing a sequence of nucleotides into a set of consecutive, non-overlapping triplets, but it is not the basic unit itself.

6. Codon: This is a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule. Codons correspond to specific amino acids.

7. Primary Transcript: This refers to the initial RNA transcript that is processed to become mRNA, but it is not the unit of the genetic code.

After analyzing the options, the correct answer is codon as it is the fundamental unit of the genetic code, providing the information necessary for coding proteins.

Final Answer

Codon
