Part 5: Completing Mutation Tables

2 pts Part 4: More Practice tracking information flow: One strand of genomic DNA (strand A, template strand) contains the following sequence reading from 5- to 3 Fill in the complementary sequence below 5-GTACGCGTATACCGA CATTC -3' Write the sequence of bases in the mRNA transcribed from template strand of DNA written 5- to 3 Write the Codons: (see genetic code table. Do not forget the start codon!) Write the anti-codons: (complementary nucleotides in tRNA) Write the amino acid sequence: (3 letter amino acid code names are fine). One more: Transcribe the following DNA strand nto mRNA and translate that strand into a polypeptide chain, identifying the codons, anticodons, and amino acid sequence DNA: CGATACAATGGACCCGGTAT GCGATATCC
