The following is a strand of eukaryotic cDNA
DNA: 5'- catgtctdacagctggccgcca- 3'
a) convert the dna above to its complementary DNA strand (must labe the 5' or 3' ends)
b) dna is converted to mrna is process is called____?
c) convert this dna (5'- catgtctdacagctggccgcca- 3') to its mrna message
d) provide the protein sequence for this dna (5'- catgtctdacagctggccgcca- 3'_
remember this is done in a standard eukaryotic cell.
