Question

What is the mRNA complementary strand for the following DNA strand:

ACC GTT AAT

Answer 1

To determine the mRNA complementary strand for the given DNA strand (ACC GTT AAT), you need to follow base pairing rules. In DNA, adenine (A) pairs with uracil (U) in RNA instead of thymine (T), and cytosine (C) pairs with guanine (G).

The base pairings for the given DNA strand are as follows:

- A (Adenine) pairs with U (Uracil)
- T (Thymine) pairs with A (Adenine)
- C (Cytosine) pairs with G (Guanine)
- G (Guanine) pairs with C (Cytosine)

Now, let's write the mRNA sequence based on the DNA template:

- DNA: A | C | C | G | T | T | A | A | T
- mRNA: U | G | G | C | A | A | U | U | A

So, the mRNA complementary strand for the DNA strand ACC GTT AAT is:
