Final answer:
To transcribe the DNA code into RNA, each base pairs with a complementary RNA base: adenine with uracil, and cytosine with guanine. Given the DNA sequence GTTAC, the corresponding RNA sequence would be CAAUG by these base pairing rules.
Step-by-step explanation:
When transcribing the DNA code into RNA, you must identify which RNA bases would pair with the DNA bases. The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G), while in RNA, thymine is replaced with uracil (U). Adenine pairs with uracil in RNA, and cytosine pairs with guanine. If we take the DNA sequence GTTAC, the complementary RNA bases that would pair with this sequence during transcription would be CAAUG.
In summary, the base pairing rules are A pairs with U (instead of T, which is in DNA) and C pairs with G. The DNA-to-RNA transcription process will read the DNA bases and create the complementary RNA strand by following these base pairing rules. This fundamental process is essential for the synthesis of proteins, which are constructed based on the sequence of bases in the corresponding mRNA, which has been transcribed from the DNA template.
