To determine the complementary mRNA strand from the given DNA template (TTC AGC), we need to first find the complementary DNA strand and then convert that to mRNA.
- The complementary DNA strand is created by pairing the bases:
- A pairs with T,
- T pairs with A,
- C pairs with G,
- G pairs with C.
So, for the given template strand (TTC AGC):
- T → A
- T → A
- C → G
- (space)
- A → U (in RNA)
- G → C
- C → G
Putting that together, we find that the complementary DNA strand is AAG TCG.
- Now, when converting to mRNA, we replace thymine (T) with uracil (U):
- AAG TCG → AAG UCG
Thus, the complementary mRNA strand for the provided DNA template (TTC AGC) is AAG UCG.
The correct response is: AAG UCG.
