ACC GTT AAT

1 answer

To find the mRNA complementary strand for the given DNA strand (ACC GTT AAT), you need to transcribe the DNA into RNA. In RNA, adenine (A) pairs with uracil (U) instead of thymine (T), while guanine (G) pairs with cytosine (C).

Let's transcribe the given DNA strand step by step:

  1. DNA: A (Adenine) pairs with U (Uracil)
  2. DNA: C (Cytosine) pairs with G (Guanine)
  3. DNA: C (Cytosine) pairs with G (Guanine)
  4. DNA: G (Guanine) pairs with C (Cytosine)
  5. DNA: T (Thymine) pairs with A (Adenine)
  6. DNA: T (Thymine) pairs with A (Adenine)
  7. DNA: A (Adenine) pairs with U (Uracil)
  8. DNA: T (Thymine) pairs with A (Adenine)

So, the DNA strand ACC GTT AAT transcribes to the mRNA strand UGG CAA UUA.

Therefore, the correct response is:

UGG CAA UUA
