MAKE CONNECTIONS Speculate about whether thesame enzyme could methylate both a histone and a DNAbase. (See Concept 5.4.)
3a) In a hypothetical cell where "wobble" pairing was not allowed (i.e. every codon must be matched by a tRNA anticodon that is its perfect complement), how many tRNAs would be required to service all of the threonine codons?
MAKE CONNECTIONS The restriction site for an enzymecalled PvuI is the following sequence:5’-CGATCG-3’3’-GCTAGC-5’
