A single-stranded DNA molecule contains 40 nucleotides with equal amounts of A, C, G, and T. This DNA strand can combine with a complementary DNA strand to form a double-stranded DNA molecule. Which is a possible sequence and structure for this DNA molecule?

#SCPH05 I Biotechnology

  1. If the single-stranded molecule has the sequence 5’-(ATGC)10, then its double- stranded form could assume a Z-DNA structure.

  2. If the single-stranded molecule has the sequence 5’-(GATC)10, then its double-stranded form could assume an H-DNA structure.

  3. If the single-stranded molecule has the sequence 5’-(CTGA)10, then its double-stranded form could assume a hairpin structure.

  4. If the single-stranded molecule has the sequence 5’-(TGAC)10, then its double-stranded form could assume a cruciform structure.
