Question 5 The action of helicase creates primers and replication bubbles DNA fragments and replication forks DNA fragments and replication bubbles primers and DNA fragments replication forks and replication bubbles O O Previous Question 6 Why does a new DNA strand elongate only in the 5' to 3' direction during DNA replication? Replication must progress toward the replication fork... The polarity of the DNA molecule prevents addition of nucleotides at the 3' end. ODNA polymerase can add nucleotides only to the free 3' end. DNA polymerase begins adding nucleotides at the 5' end of the template. < Previous Question 7 The template strand on DNA, that is used by RNA polymerase for transcription, has the sequence, 3 What will be the sequence of the transcript produced using this template? 3'-UUAACCGGUU-5' 5'-UUAACCGGUU-3' 3'-AAUUGGCCAA-5' 5'-AAUUGGCCAA-3' Previous
