1 Answer Key: Replication, Transcription, Translation Worksheet Exercise A. DNA structure You were given this DNA sequence: 3’ TACGGCATT 5’; the complete double stranded sequence would look like this (use complimentary base pairing, remember to label ends correctly): 3’ TACGGCATT 5’ 5’ ATGCCGTAA 3’ Remember although only the bases are shown above, DNA consists of deoxyribonucleotides connected via phosphodiester bonds (via -OH group of 3’ carbon of one nucleotide to phosphate of 5’ carbon on the adjacent nucleotide; form the sugar phosphate backbone). Exercise B. Replication Black letters: parental DNA; Blue color = daughter DNA. 3’ T A C G G C A T T 5’ 5’ A T G C C G T A A 3’ 5’ A T G C C G T A A 3’ 3’

Unformatted text preview: T A C G G C A T T 5 Lagging strand The diagram in the worksheet (p157) shows this area as the replication fork Leading strand (toward the fork) 2 Exercise C. Transcription. Remember RNA base pairing rules; RNA does not have thymine, it has uracil instead. Exercise D. Translation You translate the mRNA from above: 3 T A C G G C A T T 5 5 A U G C C G U A A 3 DNA mRNA 3 U A C 5 3 G G C 5 3 A U U 5 5 A U G C C G U A A 3 mRNA codons Methionine (MET) Proline (PRO) Stop charged tRNA molecules containing anticodon & attached amino acid Remember: - No tRNA for a stop codon -Each anticodon antiparallel to mRNA codon -Read the mRNA codon from the genetic code table to determine amino acid...
