Structure of RNA

This molecule in the picture must be

• DNA

• RNA

The following picture must be

• DNA because it's double stranded
• RNA because it's single stranded
• DNA because it's single stranded
• RNA because it's double stranded

What is the difference between DNA and RNA in terms of bases?

• RNA contains uracil in place of thymine
• RNA contains uracil in place of adenine
• RNA contains uracil in place of guanine
• RNA contains uracil in place of  cytosine

Which of the following are the bases for RNA?

• adenine, uracil, thymine, and guanine

• adenine, uracil, guanine, and cytosine

• adenine, thymine, guanine, and cytosine

• adenine, uracil, thymine, and cytosine

The nitrogen base pairs for RNA are

• A-T C-G

• A-U C-G

• A-C T-G

• T -U G-C

The sugar in the backbone of RNA is

• deoxyribose

• ribose

• dextrose

• sucrose

Which statement is true about RNA?

• RNA is usually single stranded and contains the base uracil

• RNA is usually double stranded and contains the base thymine

• RNA is made in the nucleus and stays there to carry out its function

• All of the above are true.
