Hydrogen bonds are important in DNA replication and transcription. They are relatively weak chemical bonds.  Why is this a desirable feature for DNA?

Describe the effect (s) of changing (mutating) the promoter on the transcription of the DNA strand/gene the promoter controls.

What happens to protein synthesis if a nonsense codon is inserted into the gene?

Explain why a point mutation does not necessarily change the original amino acid sequence. (Explain silent mutations)

Choose any pentapeptide composed of five different amino acids. List the amino acids.  Present one messenger RNA codon for each amino acids and the sequence of nucleotides on the DNA that originally coded for your pentapeptide.
