Final answer:
The RNA sequence complementary to the DNA sequence ATC is UAG. For GUA, which likely contains a typo, it would be CAG if corrected to GTC, and UAG is an RNA sequence that cannot pair with a DNA sequence without replacing uracil with thymine.
Step-by-step explanation:
The sequence of bases on RNA that would match, or pair with, a DNA sequence is determined by the rules of base pairing. In RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). Thymine (T) in DNA pairs with adenine (A) in RNA. Therefore, the RNA sequence that pairs with the following DNA sequences would be:
- For DNA sequence ATC, the RNA sequence would be UAG.
- For DNA sequence GUA, this does not provide a correct pairing since uracil (U) is not found in DNA; however, assuming it's a typo and should be GTC, the RNA sequence would be CAG.
- For DNA sequence UAG, it is important to note that thymine (T) is not found in RNA; UAG is already an RNA sequence and does not exist in DNA. But if UAG were a segment of DNA with T in place of U, the corresponding RNA sequence would be AUC.
In summary, the correct base pairing between DNA and RNA follows the rules where A pairs with U, and C pairs with G. Any typos or incorrect nucleotides should be corrected before attempting to pair the sequences.
