ATC CAG ATG AAC AGC AAT

Answer 1

To find the correct complementary mRNA strand to the given DNA template strand, we need to replace each DNA base with its RNA complement:

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

Given the DNA template strand:

**ATC CAG ATG AAC AGC AAT**

Now, we will convert each codon:

1. **ATC** -> UAG
2. **CAG** -> GUC
3. **ATG** -> UAC
4. **AAC** -> UUG
5. **AGC** -> UCG
6. **AAT** -> UUA

Putting it all together, the correct complementary mRNA strand is:

**UAG GUC UAC UUG UCG UUA**

Thus, the correct response is:

**UAG GUC UAC UUG UCG UUA**
