Question

During protein synthesis at the ribosome, the base sequence ofthe mRNA codons is translated to the amino acid sequence of aprotein.

Question: Using the mRNA that you transcribedabove, use the genetic code table to determine the resulting aminoacid sequence? Turn this in.

What is the significance of the first and last codons?What meaning do these codons have for proteinsynthesis?

A mutation is defined as a change in the base sequence ofDNA. This may occur as a “mistake” in DNA replication,for example.

Suppose that during DNA replication, two mutant DNA sequencesare produced as shown below.

For the 2 mutated DNA sequences, you will investigate how thesechanges might affect the sequence of amino acids in a protein.

It says use "the mRNA that you transcribed above," but there isnothing above you directions. You probably forgot to type it.
