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
