Cells are like fine tuned machines. They work to maintain a balance by removing what is not needed and obtaining what is. For example, if a particular enzyme such as helicase is needed, the nucleotide sequence related to that protein will be exposed and the protein made. The nucleotide bases below are an example of a segment that would be used to produce a protein. Which protein chain will be formed from this nucleotide segment? NOTE: A codon chart is provided below.

A. Cys - Leu - Pro - Thr-

B. AUGUUUGCCAACUGA

C. Met - Phe - Ala - Asn

D. Asn - Ala - Phe - Met
