Density=mass/volume
Therefore density here=3g/12mL=0.25g/mL
There are many instances in which different codons specify the same amino acid. A genetic code in which some amino acids may each be encoded by more than one codon.
Answer: Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is a cystic fibrosis.
