- Which statements are true? Explain why or why not.1 The consequences of errors in transcription areless severe than those of errors in DNA replication.2 Since introns are largely genetic “junk,” they do nothave to be removed precisely from the primary transcriptduring RNA splicing.3 Wobble pairing occurs between the first positionin the codon and the third position in the anticodon.4 During protein synthesis, the thermodynamics ofbase-pairing between tRNAs and mRNAs sets the upperlimit for the accuracy with which protein molecules aremade.5 Protein enzymes are thought to greatly outnum-ber ribozymes in modern cells because they can catalyzea much greater variety of reactions and all of them havefaster rates than any ribozyme.A.C. 3.4 Q1. Protein synthesis is carried out by the processes of transcription and translation. A short length of DNA is shown: TACTCGTCGACGATGATC First base (a) State how many codons are present.
