5. The genetic code is degenerate because
mRNA is rapidly degraded.
The code is not universal among organisms.
Some amino acids have more than one codon.
Frameshift mutations are tolerated.
Stop codons may have corresponding tRNA molecules

6. Each new DNA strand is initiated by a

Precursor fragment
Restriction fragment
Specific DNA primer
