Answer:
B (CODON)
Step-by-step explanation:
The DNA, which is the genetic material of most cells holds information that needs to be expressed. The manner in which this information is expressed is known as the GENETIC CODE. Expression follows two main processes; transcription and translation. Transcription involves making a complementary strand of mRNA from the DNA template.
The mRNA is further involved in the translation process where it is read in a group of triplet nucleotides called CODON. Each codon specifies a particular amino acid. There are 64 possible codons got from the 4 nucleotides read three at a time i.e. 4^3. The genetic code constitutes all the CODONS that specifies an amino acid.
