Answer: In the same orientation on both strands when read 5 to 3.
- A When read in one direction along a single strand only
- B On the same strand twice
- C Only after being cut
- D In the same orientation on both strands when read 5 to 3
Correct answer: D. In the same orientation on both strands when read 5 to 3
Explanation: A palindrome in DNA is a sequence of base pairs that reads the same on the two strands when the orientation of reading is kept the same (5 to 3).
Recombinant DNA technology: a gene of interest and plasmid are cut by the same restriction enzyme, ligated into a recombinant plasmid, and introduced into a host cell.
