Questions
How many nucleotides would be needed to code for a protein that has 100 amino acids?
Using the Genetic Code in Table 6.3, write all of the possible codons that signal the start and end of a gene.
Start:
End:
An amino acid sequence of a protein molecule includes methionine, lysine, serine and glycine. Show each different codon that could result in each of these amino acids. You will have more than one codon for all of them except methionine.
Amino Acids
All Possible Codons
Methionine
Lysine
Serine
(Look carefully. There are six possibilities)
Glycine
Question 3 illustrates the redundant nature of the genetic code. Can you think of an advantage of having several codons that all code for the…
