5 True/False Questions
point mutation → A mutation that doesn't detectably affect the phenotype of the organism
metabolic pathway → process by which ribosome moves down an mRNA molecules during translation
triplet code → set of 64 codons and the amino acids they specify
start codon → AUG triplet in mRNA that starts protein synthesis (stands for methionine)
codon → 3 nucleotide sequence that codes for an amino acid, or initiates/terminates protein synthesis
