What are the protein sequences encoded by repeating units of: a) GGG b) GGA c) GGC d) GGU If the sequences are read in different reading frames, how does this affect the resulting protein sequence?
The order of nucleotides is critical in determining the amino acid that is encoded. What do the following trinucleotides code for: AAC, ACA, CAA, CAC? What would be the sequence of a protein consisting of a repeat of each of these trinucleotides? If the sequence was read in a different reading frame, how would this affect th
Once it was determined that codons consisted of three-nucleotide sequences, the specificity of each codon could be determined. Using a codon table, determine what poly U codes for. Repeat with polynucleotides of the other three bases.

Why does DNA synthesis only proceed in the 5' to 3' direction? a. because DNA polymerases can only add nucleotides to the 3' end of a polynucleotide strand b. because the 3' end of the polynucleotide molecules is more electronegative than the 5' end. c. becuase that is the direction in which the two strands of DNA unzip
