The following sequence of RNA forms a “hairpin” structure.

5′-UCGUGUGCUGCACCACAGCACAAUGCU-3′

What will be the effect on the stability of this hairpin structure if the bold, underlined nucleotide is mutated from G to U?

The following sequence of RNA forms a “hairpin” structure. The duplex region contains all Watson-Crick base pairs without any gaps or mismatches.

5′-CGUAUACUAGACUGCUGGUCUAGUUACU-3′

In the space below, type the sequence of either of the two regions that form a duplex with each other.

Be careful not to type any spaces or additional characters. For example, if you think the answer is 5'-AGCC-3', simply type AGCC.

Which of the following are nucleotide subunits typically found in DNA?

One strand of a DNA duplex has the sequence:

5′-CTACAGATGT-3′

Type the sequence of the complementary strand in the 5′ to 3′ direction.

Be careful not to type any spaces or additional characters. For example, if you think the answer is 5'-AGCC-3', simply type AGCC.
