Final answer:
The genetic code is read as non-overlapping triplets called codons, each specifying a single amino acid, with no skipped bases in between, making option B the correct answer.
Step-by-step explanation:
The genetic code in an mRNA molecule is translated into a protein sequence by using three consecutive bases that are referred to as a codon. Each codon specifies a single amino acid, and importantly, there is no overlap between codons. This means that option B: 'three consecutive bases, with no overlap between triplets' is the correct answer. This codon structure ensures that amino acids are added one after another without skipping any bases, and that the protein's amino acid sequence is a linear representation of the mRNA codon sequence. Moreover, codons are contiguous; there is no punctuation between successive amino acid residues, and the reading of codons is continuous along the mRNA strand during the translation process.
