When Two Adjacent Bases in the Same Strand of DNA

question 49

Multiple Choice

When two adjacent bases in the same strand of DNA dimerize (form a covalent bond between them) , what happens to the DNA?

• A) The original strand of DNA now contains a new DNA sequence.
• B) The original strand of DNA is kinked, which prevents DNA polymerase from working properly.
• C) The original strand of DNA is methylated, which causes the bases to mismatch.
• D) The original strand of DNA is prevented from opening during replication, so this section of DNA will not be replicated.
• E) The original strand of DNA is unaffected, so no additional mutations arise.
