Group of answer choices

DNA is single-stranded while RNA is double-stranded.

DNA remains in the nucleus while RNA leaves the nucleus.

DNA contains a ribose sugar while RNA contains a deoxyribose sugar.

DNA has bases of A, G, C, and U while RNA has bases of A, G, C, and T.

Answer:

Okay, 3 of the answer choices on this are wrong. The only correct answer is "DNA remains in the nucleus while RNA leaves the nucleus."

Explanation:

1. DNA is single-stranded while RNA is double-stranded

- INCORRECT. This is the opposite. RNA is single-stranded, whereas DNA is double-stranded.

2. DNA remains in the nucleus while RNA leaves the nucleus.

- This is true because the RNA must leave the nucleus to undergo translation into a ribosome in the cytoplasm.

3. DNA contains a ribose sugar while RNA contains a deoxyribose sugar.

- INCORRECT. This is the opposite. DNA contains deoxyribose sugar, whereas RNA contains ribose sugar.

4. DNA has bases of A, G, C, and U while RNA has bases of A, G, C, and T.

- INCORRECT. This is the opposite. DNA have bases of A, G, C, T, whereas RNA has bases of A, G, C, U. RNA sequences never have the bases of Thymine (T) as the same goes with DNA sequence that does not have the base of Uracil (U).

Honestly, I don't if the question are selectable choices or only one choice answers. There are three wrong answers and one correct answer.
