To determine the RNA strand that will be produced from the given DNA strand, we need to transcribe the DNA sequence into RNA. Transcription involves creating a complementary RNA strand from the DNA template strand. In RNA, adenine (A) pairs with uracil (U) instead of thymine (T), which is found in DNA.
Given the DNA strand:
5' GCCAGA 3'
The complementary RNA strand will be synthesized in the 5' to 3' direction using the DNA template strand, which is the 3' to 5' strand. However, since only the 5' to 3' strand is provided, we will assume it is the template strand for the purpose of this exercise.
The transcription process involves the following base pairing:
- G (guanine) pairs with C (cytosine)
- C (cytosine) pairs with G (guanine)
- A (adenine) pairs with U (uracil)
- T (thymine) pairs with A (adenine) (not applicable here as there is no T in the given sequence)
Applying these rules to the given DNA sequence:
- G pairs with C
- C pairs with G
- C pairs with G
- A pairs with U
- G pairs with C
- A pairs with U
Thus, the RNA strand produced will be:
5' CGGUCU 3'
In summary, the RNA strand that will be produced from the given DNA strand is 5' CGGUCU 3'.
