Final answer:
The codon sequences for leucine in mRNA are UUA, UUG, CUU, CUC, CUA, and CUG. Each of these codons will code for leucine during protein synthesis, illustrating the degeneracy of the genetic code.
Step-by-step explanation:
The codon sequences for the amino acid leucine are specific sets of three nucleotides that correspond to this amino acid according to the genetic code. In messenger RNA (mRNA), leucine is represented by six different codons. These codons are UUA, UUG, CUU, CUC, CUA, and CUG. Each of these triplets, when present in the mRNA sequence, will code for the incorporation of a leucine residue into the growing polypeptide chain during the process of protein synthesis.
Understanding the genetic code is crucial for areas such as molecular biology, genetics, and bioinformatics. It provides the necessary details for decoding mRNA sequences into amino acid sequences of proteins. Leucine is one of the amino acids with multiple codons, demonstrating the 'degeneracy' of the genetic code, where multiple codons can specify the same amino acid.
