question 24

Multiple Choice

• A) They lack the 3' OH that would permit them to be covalently linked to the Okazaki fragments.
• B) The primers do not hydrogen bond to the template strand correctly.
• C) They contain nucleotides with 2'OH groups, and are targeted for excision by DNA Polymerase.
• D) They have to be removed for leading and lagging strand synthesis to begin.
• E) Primers are too short to efficiently bind to Okazaki fragments.
